automate the release process

[arademaker]

If you wish to distribute your release on GitHub, I recommend setting up a GitHub Action that does the following when a new release in GitHub is created:

• validates the lexicon
• creates the WN-LMF package
• compresses the package
• uploads the package as a release asset

See OdeNet's workflow for an example. And I'm happy to answer questions about it.
