Updates and checking of user manual

As someone supporting IBEX I want the user manual to be as up to date as possible so that it is useful to those that need it.

As part of a Friday/Tech Debt day, this was started with the following completed and noted:

Sections reviewed and updated:
- [x] What Is IBEX - simplified the first page, moved the SECI comparison to a new page
- [x] Getting Help / Reporting Problems - no changes link takes you to the right bit of the FAQ, consider this there
- [x] Installing IBEX - Gutted a lot of the detail that was on this page (including full paths to directories...) this will need a rethink as to how we make the client available for download
- [x] Starting And Stopping IBEX - simplified to match the current situation on instruments
- [x] Key Concepts in IBEX - updated EPICS link
- [x] Instrument Specific Guidance - these seemed OK to me, at least what is there is OK
- [x] The Web Dashboard - seemed fine to me
- [x] FAQ Including scripting - only bit that really needed updating was the guidance on where to look for what is being worked on
- [x] Glossary - mostly OK, just the DAE description

Sections to be reviewed:
- [ ] IBEX GUI Features - needs new images, the extra behaviours adding
- [ ] How To Do Things In IBEX - needs new images, and I think by now it is missing quite a few routes through
- [ ] Scripting - feels like it is more out of date than it ought to be, need to remove the python 2 aspects
- [ ] The IBEX Script Generator
- [ ] Device Specific Guidance - There is some extra info needed on the Eurotherm, need to check about the FZJ choppers, the matplotlib is beyond my knowledge off the top of my head, otherwise I think everything looked OK, and the Reflectometry section had been updated by NR in November 2022, so should be fairly close to accurate
- [ ] Python-3 - Whether or not this is still needed would be best verified by someone else, as I'm not sure it is

Other things to consider/do in the future:
- [ ] Detail the need for a rethink of what we make available for download, and how we make them available
- [ ] Remove the notes regarding switching to and from SECI from the starting and stopping section of the IBEX manual
- [ ] Create advance PI planning boards for a few years (e.g. each of the PIs to the end of the IBEX project, plus a few more, this will allow notes of things that need to be done before/after big projects to be noted)
[ ] @FreddieAkeroyd to update the DAE section on Key Concepts in IBEX (https://github.com/ISISComputingGroup/ibex_user_manual/wiki/Key-Concepts-in-IBEX#id10) and in the glossary (https://github.com/ISISComputingGroup/ibex_user_manual/wiki/Glossary). Whilst those read true for DAE2, DAE3 does something different, and there is a very high chance that the Endeavour instruments will do something different again
[ ] Add a note to a future PI (once it is possible) to update the Scripting page to de-emphasize conversions from open genie to genie_python once IBEX is done
[ ] Update the Eurotherm guidance on https://github.com/ISISComputingGroup/ibex_user_manual/wiki/Eurotherm as it should probably reference the file format and information to help understanding for the calibration files too
[ ] @davidkeymer to check that https://github.com/ISISComputingGroup/ibex_user_manual/wiki/FZJ-Fermi-Chopper is still valid and reading appropriately
[ ] Look at the matplotlib guidance (https://github.com/ISISComputingGroup/ibex_user_manual/wiki/Matplotlib) to make sure that is still valid

Start by reviewing the unchecked sections in the IBEX user manual, especially IBEX GUI Features, How To Do Things In IBEX, Scripting, the IBEX Script Generator, and Device Specific Guidance. The issue also identifies the Eurotherm, FZJ Fermi Chopper, Matplotlib, Key Concepts, and Glossary pages for specific checks. Done is not narrowly defined; each selected section should be reviewed and its outdated content or images updated.
