This change fixes the last of the spelling issues, and enables the pre-commit (and CI) check for spelling. There are no functionality changes, but it does rename some enum values.
This change renames all occurrences of `rippled.cfg` to `xrpld.cfg`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts. For the time being it maintains support for `rippled.cfg` as config file, if `xrpld.cfg` does not exist.
