Uploading new versions of the plugin to the WordPress store

Here is how you upload a new version.

1. Update the Version: <version> in index.php.
2. Add a changelog entry for the new version to readme.txt.
3. (optional) Update version numbers strewn about various php files (like class-wc-gateway-komoju.php).
4. Run git tag <your new version>.
5. Run git push --tags.
6. GitHub Actions should deploy for you.

One thing to note: as of writing, the deploy action does not depend on the test action passing. You should make sure tests pass before running git push --tags - or maybe change the actions so that deployment depends on tests!
