Can I let someone handle the changeset part? I run npx changeset but got
npm ERR! could not determine executable to run.

@inwardmovement Try pnpx changeset instead?

pnpx: The term 'pnpx' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

I'm new to changesets, there may be something I'm not doing well

@inwardmovement Thanks for opening the PR, and welcome to the growing list of Astro contributors!

I just added a changeset to the PR 👍 Looks like you opened the PR right from GitHub's edit link, changesets can be a little annoying there since you still end up having to sync down the branch anyway 🙃

Approved! Thanks for the assist @tony-sull!
