mailpit in place now
I have tested this item ✅ successfully on 7a3763c
Created first Codespace on 5.4-dev and tested Home Dashboard > Global Configuration > Server > Send Test Mail fails with red 'Could not instantiate mail function.'
✅ Created second Codespace on this PRs add-mailhog branch. Repeated the test and got green 'The email was sent to admin@example.com using SMTP.' Additional on port 8025 I could read and delete the email with Mailpit.
✅ Additional tested System > Scheduled Tasks > Session GC > Advanced > Enabled Task Success Notifications and run Session GC test run and got the email in Mailpit.

Thank you @alikon for your contribution. Thank you @wilsonge for your support. Thank you @richard67 and @exlemor for testing.
Mail hog seems to be dead from a support perspective - no commits in several years. Laravel moved to mail pit. Can we try that instead or something similar?
