Releasing Taskwarrior

To release Taskwarrior, follow this process:

Create a release PR
- Update version in CMakeLists.txt
- Update Changelog
- get this merged
On develop after that PR merges, create a release tarball:
- git clone . release-tarball
- cd release-tarball/
- edit Cargo.toml to contain only taskchampion and taskchampion-lib in members (see https://github.com/GothenburgBitFactory/taskwarrior/issues/3294).
- cmake -S. -Bbuild
- make -Cbuild package_source
- copy build/task-*.tar.gz elsewhere and delete the release-tarball dir
- NOTE: older releases had a test-*.tar.gz but it's unclear how to generate this
Update stable to the released commit and push upstream
Tag the commit as vX.Y.Z and push the tag upstream
Find the tag under https://github.com/GothenburgBitFactory/taskwarrior/tags and create a release from it
- Give it a clever title if you can think of one; refer to previous releases
- Include the tarball from earlier
