FF90 - remove ftp

[hamishwillee]

Fixes #5388

FTP was removed from Firefox in FF90. This PR:

• Updates release notes
• Removes the preference from experimental features
• A few other cosmetic improvements to FTP related pages as I came to them.

It does not remove the proxy setting for FTP (as that has not been reomved)

I previously removed most relevant stuff for FF88 so not much to do.

Rob tells me that the requested change is not needed (proxy was not removed)
