Concatenate error in checkIfPRContentChanged (#28731) (#28737)

Browse source 
Backport #28731 by @earl-warren

- If there's a error with the Git command in `checkIfPRContentChanged`
the stderr wasn't concatendated to the error, which results in still not
knowing why an error happend.
- Adds concatenation for stderr to the returned error.
