Automatic checks on submission

Need to automate the checks. Eg

• Files are in expected locations and right casing
• key files, README.md, in assets, preview.png and sample.json
• sample.json must not be default BUT if it is to support the contributor, its a task for ME.
• Parts of the Readme needed to be updated (need to expand on detail)
• telemetry url in right format matches the folder name
• delete cmdlet have warning in place in the readme file
• dates are up to date - ensure that dates created/modified are not part of the default template e.g. there is a change.
• Recent issue the name column in sample.json file shouldn't contain special characters

Ideally, the list shouldnt be a barrier, its more of a helper for me to tweak the submission accordingly (so i don't miss anything) and contributor gets help.

• For each step thats checked - ensure there is contributor guidance to help the contributor.
