Self-review + reviewer's template

• rbm.conf updates:
  • var/torbrowser_version
  • var/torbrowser_build: should be build1, unless bumping a previous release preparation
  • var/browser_release_date: must not be in the future when we start building
  • var/torbrowser_incremental_from (not needed for Android-only releases)
• Tag updates:
  • Firefox
  • Geckoview - should match Firefox
  • Firefox Android
  • Tags might be speculative in the release preparation: i.e., they might not exist yet.
• Addon updates:
  • NoScript
  • uBlock Origin (Mullvad Browser only)
  • Mullvad Browser Extension (Mullvad Browser only)
  • For AMO extension (NoScript and uBlock), updating the version in the URL is not enough, check that also a numeric ID from the URL has changed
• Tor and dependencies updates (Tor Browser only)
  • Tor
  • OpenSSL: we stay on the latest LTS channel (currently 3.0.x)
  • zlib
  • Zstandard (Android only, at least for now)
  • Go: avoid major updates, unless planned
• Manual version update (Tor Browser only, optional)
• Changelogs
  • Changelogs must be in sync between stable and alpha
  • Check the browser name
  • Check the version
  • Check the release date
  • Check we include only the platform we're releasing for (e.g., no Android in desktop-only releases)
  • Check all the updates from above are reported in the changelogs
  • Check for major errors
    • If you find errors such as platform or category (build system) please adjust the issue label accordingly
    • You can run tools/relprep.py --only-changelogs --date $date $version to update only the changelogs

Change Description

Usual release preparation.

We might need to bump the tags if there are Android backports (cc @ma1) and update the changelogs accordingly.
