Test Email Sending: Save email content to local .wrangler directory instead of system tmp directory

[patsaas]

When testing Email Sending locally (remote: false) we are wanting to save emails to the project's .wrangler directory instead of the system tmp directory where the path is quite obscure (macOS here).

This would unlock automated testing, allowing us to check email contents for auth links/etc., and it would replace a few other tools we use like Nodemailer, InBucket, Mailpit.

Currently documented here:

Thanks for the feature request! Just to understand this more, do you want:

• an easier/more stable path to access the emails (e.g .wrangler/tmp)
• persistence across dev sessions

or both?

.wrangler/tmp would be perfect! I can't think of a good reason to persist local emails.
