Tag released versions

[WarningImHack3r]

Hi maintainers, I'm the creator of Svelte Changelog, a site that tracks all the releases by the Svelte organization.

To list releases, I leverage the GitHub API in 2 ways:

• list GitHub releases if available
• reconstruct releases from the list of tags, with the release body constructed from the root CHANGELOG.md file

As a result, releases not listed in the releases nor in the list of tags are not caught by the site.

This repo is the only one I can tell from the sveltejs org that has a few divergences from the other ones: the latest CHANGELOG.md file is in the special version-3 branch instead of master, but most importantly, the last two releases are not tagged at all, making them invisible from my site's perspective.

I could adjust my research algorithm to take the most recent source between the list of tags and the CHANGELOG.md file, but it's a far less reliable method and adds up quite a bit of code to specifically handle the case of this repo.

As a result, can you please make sure new releases for this repo are tagged accordingly? This would help Paolo during TWIS, but also all the other users of Svelte Changelog ^^ Thanks!!
