Release 0.0.97 beta

[KitsuneRal]

Pre-check:

• There are no pending issues in the Roadmap for this release (if there are, move them away or close them)
• Check the correct branch/commit:
  • in the Quaternion repo
  • Quotient repo submodule ref
  • CI:
• Make sure the required version of libQuotient in CMakeLists.txt is up-to-date
• Pull translations
  • If needed, update the list of languages in CMakeLists.txt
  • Unset the branch tag after merging
• Check that documentation is up to date:
  • README.md
  • SECURITY.md
  • BUILDING.md
• Rebuild and smoke-test the application
• If quaternion_en.ts is changed, review, commit and push the changes before proceeding

Actions:

• Go to the Releases page and make a new draft:
  • Set the tag (N.M.L, must not exist yet)
  • Describe all notable fixes/enhancements
• Update the version number in main.cpp and CMakeLists.txt
• Add a release record to linux/io.github.quotient_im.Quaternion.appdata.xml
  • Copy a summary of changes from the draft at GH to the release <description>
• git commit
• git tag -a N.M.L && git push --follow-tags
• Update Flathub repo
  • Ask to make a test build
  • Download and smoke-test the binary (check the version!); if something is off, delete the tag locally and on remotes, fix-commit-push, check that GitHub Actions are green, set again and push the same tag; a new Flathub build should start automatically
  • PR merged
• Publish release notes
  • Update the Releases Wiki page
• Update the topic in #quaternion
• Post a TWIM update

Post-release:

• Open the release page in Incognito/Privacy mode; check:
  • the version
  • the Git tag
  • Check the pre-release checkbox if this version is a beta or release candidate
• Add '+git' to the version number in 'main.cpp'
• git commit && git push
