Subject: [PATCH] [CI:DOCS] Add GitHub action to update version on Podman.io

Introduce a new GitHub action that will update Podman.io to the newest version of Podman. This action will run on a release being published to GitHub, or by clicking the run workflow button on GitHub. The action will check if the release version is higher than the current version on the website, and open a PR to update the version if a PR does not already exist. The commit will be signed off by the user who triggered the action, so whoever creates the release or presses the run workflow button. The PR will be opened by the podmanbot GitHub account.
