fix(shim): Check literal path in Get-ShimPath

[lewis-yeung]

Description

A run of scoop shim info scoo* shows this:

Name     : scoo*
Path     : <SCOOP_ROOT>\shims\scoo*.ps1
Source   : scoop
Type     : ExternalScript
IsGlobal : False
IsHidden : True

Related code:

Scoop/libexec/scoop-shim.ps1

Lines 82 to 89 in f930280

	function Get-ShimPath($ShimName, $Global) {
	'.shim', '.ps1' | ForEach-Object {
	$shimPath = Join-Path (shimdir $Global) "$ShimName$_"
	if (Test-Path $shimPath) {
	return $shimPath
	}
	}
	}

A name containing wildcard characters (e.g., *) is directly passed to Get-ShimPath here and the returned path still contains wildcard characters.

This is not expected according to the usage of scoop shim info <shim_name>. No characters should be interpreted as wildcard characters here.

Motivation and Context

Fix the bug.

How Has This Been Tested?

Run:

scoop shim info scoo*
scoop shim info scoo* -g

Output:

ERROR: Local shim not found: scoo*
ERROR: Global shim not found: scoo*
