Use correct token in release trigger workflow

[douglowder]

Why

Release trigger workflow was working correctly otherwise, but was not using the Git token for the Expo bot, so could not push to main.

How

Modify workflow to use the correct token.

Test Plan

Just successfully triggered a release, showing that the fix is working.
