Steps for releasing `matrix-rust-sdk-crypto-nodejs`

Create a new branch, named release-v<version>.
Update CHANGELOG.md and git add ready for commit on the next step.
Run yarn version to bump the version number, commit, and create a tag.
Push the branch, but not yet the tag.
Create a PR to approve the changes.
Once approved:
1. Update the git tag to the new head of the branch, if necessary.
2. Push the git tag (git push origin tag v<version>). Doing so triggers the github actions workflow which builds and publishes to npm, and creates a draft GH release.
3. Merge the PR. (Prefer a genuine merge rather than a squash so that the tagged commit is included in the history.)
Update the release on github and publish.
