Bug 1715248 - include upload-symbols tasks in desktop release promotion. r=releng-reviewers,taskgraph-reviewers,gbrown

Usually, upload-symbols tasks run as part of the on-push graph; however, if a
push only touches platform-specific code, builds for other platforms may get
optimized out, along with the corresponding upload-symbols tasks.  If release
promotion is triggered on such a push, we may end up shipping builds whose
symbols are missing from the symbols server, affecting downstream consumers
like crash-stats.  To avoid this, ensure beetmover jobs (as an arbitrary
choice) pull in the upload-symbols tasks.
