Old pinned Astro version causes security vulnerability

[ivan94fi]

This issue is a development of #176.

The actual pinned Astro version is old and causes a security vulnerability: GHSA-67mh-4wv8-2f99

Can you please bump the dependency to the latest Astro?

Thank you

I used to use this library and even had donated to it and attempted to run a fork.

Unfortunately I think @castarco isn't currently maintaining it at the moment.
