tools: Add releaser for helping manage and automate the release process

[joaquimrocha]

Over the past releases, I have been adding changes to this branch and testing it. Yet with the move to kubernetes-sigs maybe a few things may be broken. Let's still try to get it in and fix them afterwards if it happens.

Matching the release using the 'name' property may lead to issues if the naming convention does not strictly match the version. Consider using 'tag_name' for comparison or ensure that release names are always set to the version string.

Suggested change

	const draft = releases.find(release => release.name === version);
	const draft = releases.find(release => release.tag_name === version);
