feat(core): Add -Quiet switch for Invoke-ExternalCommand

[lewis-yeung]

Description

In function Invoke-ExternalCommand, the $Process.StartInfo.CreateNoWindow was forcibly set to $true by mistake in #5066, which may cause problems in some cases. In this PR, a -Silent -Quiet switch was introduced. The switch controls whether an app should run silently, that means, without any output for a console app or without a window for a GUI app.

Checklist:

• I have read the Contributing Guide.
• I have ensured that I am targeting the develop branch.
• I have updated the documentation accordingly.
• I have updated the tests accordingly.
• I have added an entry in the CHANGELOG.

Ed. LGTM except for the param name.

Hmm, renaming to $Quiet? Ref: https://learn.microsoft.com/en-us/powershell/scripting/developer/cmdlet/activity-parameters?view=powershell-7.3

Quiet
Data type: SwitchParameter
Implement this parameter so that the cmdlet suppresses user feedback during its actions when the parameter is specified.
