Update to Astro `>=5.2.0`

[pgerhard-twks]

Hi y'all,

Thanks for creating this great template. Just what the timeline for updating it to a version of Astro >=5.2.0? This version changes how Tailwind CSS is integrated and unfortunately this is not compatible with the Tailwind integration as provided in the current version of the template

@pgerhard-twks I've just made a PR with all the dependencies updated, and it's working with the latest version of Tailwind CSS, you can check it while the PR is approved and merged.
