imap-send doc: omit confusing "to use imap-send" modifier

It wouldn't make sense for these configuration variables to be
required for Git in general to function.  'Required' in this context
means required for git imap-send to work.

Noticed while trying to figure out what the sentence describing
imap.tunnel meant.

[jn: expanded to also simplify explanation of imap.folder and
 imap.host in the same way]
