implement semver comparison for winget version detection

[a-mnich]

Proposed Changes

SemVer version comparison

Switch to actual SemVer version comparison for the available / installed version detection.
WinGet distributes "-preview" versions for participants of the insider program which currently isn't supported by the version comparison. This causes WAU to fully download and install an older WinGet version on every run even though the preview version is actually newer.

$WinGetAvailableVersion = "1.9.25200"
$WinGetInstalledVersion = "1.10.40-preview"

$WinGetAvailableVersion -gt $WinGetInstalledVersion
-> True (wrong)

Compare-SemVer -Version1 $WinGetAvailableVersion -Version2 $WinGetInstalledVersion
-> -1 (available is lower then the currently installed version)

$WinGetAvailableVersion = "1.10.40"
$WinGetInstalledVersion = "1.10.40-preview"
Compare-SemVer -Version1 $WinGetAvailableVersion -Version2 $WinGetInstalledVersion
-> 1 (available is greater then the currently installed version -> correct)

$WinGetAvailableVersion = "1.9.25200"
$WinGetInstalledVersion = "1.8.0"
Compare-SemVer -Version1 $WinGetAvailableVersion -Version2 $WinGetInstalledVersion
-> 1 (available is greater then the currently installed version -> correct)

$WinGetAvailableVersion = "1.9.25200"
$WinGetInstalledVersion = "1.9.25200"
Compare-SemVer -Version1 $WinGetAvailableVersion -Version2 $WinGetInstalledVersion
-> 0 (available is equal to the currently installed version -> correct)

replace Replace with TrimStart

v1.10.40-preview was currently detected as 1.10.40-preiew due to Replace("v", "").
TrimStart("v") fixes this.
