Downgrading from astro 7 to astro 6 fixes this issue

Downgrading from astro 7 to astro 6 fixes this issue

IIRC, this was one of the changes that came with the new Astro v7 compiler system, they changed the rules a bit to require some extra wrapping instead of being able to just use the script like previously (See PR #1556 for example)

---

To be clear, StudioCMS does not yet officially support Astro 6/7 (Currently the project's build target is Astro v5 still) as that was still being worked on before i had to stop and take a break from development to deal with some IRL stuff.

The WIP PR which currently includes proper Astro v6 support is here: #1484
