doc: escape internal ">" in listid code snippet

A code snippet in the listid description is incorrectly rendered as

    "publicinbox.$NAME.watchheader=List-Id:<foo.example.com">

Escape the closing bracket around the List-Id value to avoid this.
Also escape the opening bracket for symmetry/readability.

 For public-inbox-watch users, this is a shortcut for specifying
-C<publicinbox.$NAME.watchheader=List-Id:<foo.example.com>>
+C<publicinbox.$NAME.watchheader=List-Id:E<lt>foo.example.comE<gt>>
 
 For public-inbox-mda users, this may be used to avoid recipient
 matching via C<ORIGINAL_RECIPIENT> environment variable.
