Test the snapshot by intalling your package globally:

pnpm i -g shopify@0.0.0-snapshot-20240806161156

After installing, validate the version by running just shopify in your terminal
If the versions don't match, you might have multiple global instances installed.
Use which shopify to find out which one you are running and uninstall it.

Should I be including a changeset entry for this change? I didn't on the original change because it should have been invisible to the end user.

@jeffcharles This definitely needs a patch-level changeset if we will be releasing the bugfix as a patch to the current minor version. Otherwise the release system won't be able to increment a version.
