DomainMOD v4.22 Released -- Maintenance Update

There's not a whole lot to report on with this release, as it was mostly some small maintenance tasks.

Some of the work done in this release includes:

• Updated to a new currency converter that will hopefully stick around for a while
• Updated the Porkbun API URL
• Fixed a couple bugs that caused the Add Domain and Add SSL Cert buttons to not display in rare situations
• Fixed a handful of menu items that were still hard-coded in English and weren't being translated into other languages

Other than the above items this release was mostly just software dependency and copy updates.
