Paywalls: update snapshot generation with new separate git repo (#3116

)

Follow up to #3115.

Note that this won't update the commit that the branch is pointing to.
But one all PRs are merged, one can easily update that one commit in
your local PR.

Example:
https://github.com/RevenueCat/purchases-ios-snapshots/pull/4/files
