…to prevent scheduler crash (#64503) Closes #63926 StaleDataError raised by SQLAlchemy's optimistic locking when a concurrent session modifies the same row can cause the scheduler to crash during verify_integrity. Fix by catching StaleDataError alongside IntegrityError in dagrun.verify_integrity() and adding it to the retry exceptions in run_with_db_retries()/retry_db_transaction() so the operation is retried automatically. (cherry picked from commit dcfa271) Co-authored-by: Pradeep Kalluri <128097794+kalluripradeep@users.noreply.github.com>

Closes #63926
StaleDataError raised by SQLAlchemy's optimistic locking when a concurrent
session modifies the same row can cause the scheduler to crash during
verify_integrity. Fix by catching StaleDataError alongside IntegrityError
in dagrun.verify_integrity() and adding it to the retry exceptions in
run_with_db_retries()/retry_db_transaction() so the operation is retried
automatically.
