Make commands consistent

Several small inconsistencies
- Currently there are many PMC commands for which we don't include the dotnet CLI equivalent in the documentation, although it applies
- Sometimes we use `PM>`, sometimes not, sometimes we just say Run or Execute and include the command inline.
- We should consider making it so that it is always possible to click on Copy button and then paste on the real command line
- Perhaps use PowerShell blocks for PMC, something else for dotnet CLI and other commands.
- We should use tabs to show the different ways to do the same thing
