Many small fixes:
- Clarify that `mc legalhold set --recursive` applies to current objects
only. Go back and do it again if you want it to apply to newly created
objects.
- Clean up inconsistent capitalization of "legal hold."
- Fix a bunch more `:required:` and `:optional:`
- Add a resync step to the restore site replication instructions
