fix(shim): Fix PS1 shim error when in different drive in PS7

[niheaven]

Description

Fix PS1 shim's content switch, change from ^(.\\[\w]:).*$ to ^(\.\\)?\w:.*$. Also enclose shim content with @() for a clear look.

Motivation and Context

PS1 shim went wrong in PowerShell 7 if target is in a different drive other than shim dir. This is introduced by Resolve-Path -Relative cmdlet's output.

In PS5:

In PS7:

Other changes are pure refactoring (enclosed raw code in @())

How Has This Been Tested?

@rashil2000 Could you please check enclosed code? I do this carefully and think they haven't changed 😄

It's only refactoring and makes them look prettier.

[rashil2000]

Only one minor thing: Some places use '' to enclose strings, while some use "". I know "" is used only in places that have string literals, but I think we should try to be consistent instead. Mixing them up reduces readability.

Well, the two different quotes are introduced by PowerShell formatter, I'll change them all to " for better readability.

It should be done.

@rashil2000 Could you please add some tests for newly added shims? e.g., jar, python or other types.

[rashil2000]

Sure!

But I have never written tests for PowerShell before. Could you point at some examples in the codebase I can look at?
