Subject: [PATCH] [fix][googlecloudmonitoringreceiver]: remove creds check
 (#36648)

#### Description
Fix "no validation found" error if workload is running on Google Cloud
Platform.
There's no need to check for `creds` or `creds.JSON` explicitly. If any
errors are encountered, it will be thrown by `FindDefaultCredentials`.

<!-- Issue number (e.g. #1234) or full URL to issue, if applicable. -->
