Add workflow_dispatch to trigger build manually

Shopify's bot's PR's preview build work correctly (https://01hsy7xbvc9wwerachj9xjb8aw-1e6e21ecac686203357d.myshopify.dev/), but once merged, it doesn't anymore (https://01hsy7wztzwpyrb32vgeckevsx-1e6e21ecac686203357d.myshopify.dev/).

Hopefully it was just a glitch and rerunning the build will fix it. Otherwise, we'll revert the merge.
