Rollup merge of #139038 - adamgreig:thumb-target-maintainers, r=Noratrieb

Update target maintainers for thumb targets to reflect new REWG Arm team name

Closes #139027

The name of the team responsible for these targets has changed as the team was merged with other Arm-related teams (see rust-embedded/wg#818). The link gives an up-to-date list of github usernames that can be pinged, whereas the old email address is not very actively maintained or tracked.
