Action to Automatically Create Release

[LiamMahoney]

Need to create a GitHub action that will automatically create a release when a new version is released.

Should either be triggered on PR being merged or a push into the default branch.

Release details:

• should use the description / body of the PR as the release description
• create tag - probably using this wrong, I need to look into it more
• use python version as release + tag name
• upload distribution archive files

Thought this would be easier than it appears to be. Might need to become familiar with javascript actions so I can use the GitHub API within the action.
