Update to 91.2.0 in impish

[Olivier Tilloy]

impish currently has thunderbird 1:91.1.2+build1-0ubuntu1, which at the time of filing this bug is the latest stable release (so all is good).

There is a new release candidate, 91.2.0+build1 (https://ftp.mozilla.org/pub/thunderbird/candidates/91.2.0-candidates/build1/) which, if everything goes fine, will become a release before impish is released.

I intend to upload that RC to impish-proposed, so I'm filing this bug for the release team to decide whether it's worth accepting in the release, or leaving it out as a 0-day SRU.

Hi Olivier,

This didn't get accepted prior to release, so it's now in the SRU queue. If you want this to be an SRU now, we're missing an SRU template for it here. Thanks!

Mozilla products (including thunderbird) have a standing micro-release exception (see https://wiki.ubuntu.com/SecurityTeam/PublicationNotes#Mozilla), and as this update contains security fixes (https://www.mozilla.org/en-US/security/advisories/mfsa2021-47/) we'll go that route instead. Feel free to reject from the queue. Thanks!
