send-pack: specify --force-with-lease argument help explicitly

Wrap each part of the argument help string in angular brackets to show
that users need to replace them with actual values.  Do that explicitly
to balance the pairs nicely in the code and avoid confusing casual
readers.  Add the flag PARSE_OPT_LITERAL_ARGHELP to keep parseopt from
adding another pair.
