CLI: -STA and -MTA are mistaken for a -File parameter value #4350
Description
Note: -STA and -MTA are not supported in Core, but for consistency with Windows PowerShell, they should still be recognized, and either an error or a warning should be reported.
Here you can see that checking for -STA and -MTA is simply bypassed in Core.
Steps to reproduce
powershell -staExpected behavior
An error or a warning about how -STA and -MTA are not supported in PowerShell Core.
Actual behavior
-sta is misinterpreted as an (implied) -File parameter value; an error message is reported, and the session is exited.
The argument '-sta' to the -File parameter does not exist. Provide the path to an existing '.ps1' file as an argument to the -File parameter.

Agree that we should error out so that existing Windows PowerShell scripts fail more gracefully
