[ANNOUNCE] Taskcluster patch-version upgrade to 44.11.2

[Andrew Halberstadt]

As per Aki's prior post to dev-platform, the Taskcluster, CloudOps, and Releng teams are planning on rolling out a Taskcluster version upgrade to the FirefoxCI cluster every second Wednesday. The first such regularly scheduled upgrade will be today April 20th in ~1 hour.

Timeline:

- Upgrade the cluster at 3pm UTC / 8am PDT
- Finish by 3:30pm UTC / 8:30am PDT; respond to this email.

So far the no-tree closure upgrades have been working smoothly so we're planning on following that model going forward. If there is more disruption than expected, ideally we can identify what we need to fix to make non-tree-closure maintenance possible.

This upgrade will bring us from 44.11.1 to 44.11.2. This is a patch upgrade which only includes dependency updates (this release is more about getting us on a regularly scheduled train).

Please let us know if you have any questions or concerns.

Backchannels:
- Slack: #firefox-ci-proj (primary) and #taskcluster-cloudops
- Matrix: #releaseduty and #firefox-ci

The update is now complete.

We don't see any busts, but please let releng or the sheriffs know if you have any problems/questions/concerns.

Thank you.
