LiveShare: Improve support for dirty readonly files #53257
Description
Issue Type: Bug
When an extension applies edits to the documents opened from a read-only file system provider, the document becomes marked as 'dirty' but saving it always fails with an error "Failed to save 'file.ext': Insufficient permissions. Select 'Retry as Admin' to retry as administrator." Retrying as administrator does nothing and repeats the error.
