Bookshop Browser v3.10.0 is broken for Astro projects

[adon-cloudcannon]

It appears that the Bookshop Browser won't run in an Astro project in v3.10.0 (perhaps other SSGs, untested).

Steps to recreate

1. Create a new Astro project with default setup
2. Add Bookshop v3.10.0 as per these docs
3. Add the sample component
4. Try to run Bookshop Browser with npx @bookshop/browser

Following error message:

Node.js v20.12.2

Reverting Bookshop back to v3.9.0 works.
