Upload a GitHub release to Zenodo

This is a Github action to update your codemeta.json, CITATION.cff and .zenodo.json files with the release information and then upload your release to Zenodo.

This action uses the tag name of the release to update the version field in the metadata files. Be sure to use the correct tag name. Within your tag name a valid semver version should be present.

When update metadata files are added to your repository, the action will automatically send the new metadata files in its release. This will also mean that your Github release will not contain the updated metadata files. To avoid this, you can set the update_metadata_files option to false and add a .zenodo.json file.

Remember to remove the webhook from your repository before using this action. Otherwise, you will have two releases on Zenodo for every release on Github.

Currently the following files and fields will be updated:

* `codemeta.json`:
    * `version`: The release version
    * `identifier`: The release identifier (Zenodo version specific doi)

* `CITATION.cff`:
    * `version`: The release version
    * `identifiers`: The release identifier (Zenodo version specific doi).
    This action currently assumes your old zenodo doi is the first item in the list.

* `.zenodo.json`:
    * `version`: The release version

* `docs.compatibility.json`
    * A new entry will be added in this file. This entry is meant for versioned Docusaurus projects
        * `docsVersion` - The new docs version
        * `appVersion` - The latest app version
