Trivial layout issue on ProFTPD Server config page

SYSTEM INFORMATION
OS type and version REQUIRED
Webmin version REQUIRED

page: proftpd/?xnavigation=1

where text reads:
“Click this button to start the FTP server with the current configuration. You can also configure the server to be started automatically when needed using theInternet Servicesmodule”

needs a space between ‘Internet Services’ and ‘module’

We should remove that text entirely, as inetd (or xinetd, more likely) is deprecated on modern Linux systems. The modern alternative is systemd socket activation, but we don’t really have Webmin support for setting up or managing socket activated services, and most people using ProFTPd should probably just leave it running all the time; it’s quite small.

This PR removes that text altogether, at least in the languages I can read well enough to edit, and I guess the auto-translated files will follow.
