Fix clone failure on Windows for branch names with single quote

What does this MR do?

This MR makes sure branch names with apostrophes don't break the git clone command on Windows, by wrapping git.BuildInfo.Refspec with single quotes and double quotes.

Why was this MR needed?

Windows Runner fails to clone branches contain a single quote (') in his name with this error:

Preparing the "shell" executor

Created fresh repository.

ERROR: Job failed: exit status 128

What's the best way to test this MR?

Create a branch with single quote (') in his name (e.g Test's ) ( Make sure GIT_STRATEGY isn't none or empty).
