Fix side effect logic in ReleaseTools module
This uses a new function `Use-Repository` that executes the given script with the given repository as the current working directory, replacing all the previously side effect driven logic, or at least, making it more explicit. This was frankly easier than dealing with the Azure Pipeline that clones the repository under a different name (specifically `s` if its the only repo, that is, it's not named `vscode-powershell` in the release stage, so the module broke).
