#2538 af4f27c5 Thanks @edevil! - feat: support EmailEvent event type in wrangler tail.
#2404 3f824347 Thanks @petebacondarwin! - feat: support bundling the raw Pages _worker.js before deploying
Previously, if you provided a _worker.js file, then Pages would simply check the
file for disallowed imports and then deploy the file as-is.
Not bundling the _worker.js file means that it cannot containing imports to other
JS files, but also prevents Wrangler from adding shims such as the one for the D1 alpha
release.
This change adds the ability to tell Wrangler to pass the _worker.js through the
normal Wrangler bundling process before deploying by setting the --bundle
command line argument to wrangler pages dev and wrangler pages publish.
This is in keeping with the same flag for wrangler publish.
Currently bundling is opt-in, flag defaults to false if not provided.

#2528 18208091 Thanks @caass! - Add some guidance when folks encounter a 10021 error.
