[PATCH v2 1/3] credential: make -h output and SYNOPSIS agree

[Wasswa Edson <edsonwasswa54@gmail.com>]

The usage string of "git credential" does not mention the
"capability" subcommand, even though it is documented and
implemented. The SYNOPSIS in its documentation does list it, but
is written as a plain literal block instead of using [verse], so
t0450 cannot extract it, and "credential" has been listed as a
known mismatch between the "-h" output and the documentation.

Add "capability" to the usage string, mark the SYNOPSIS as
[verse], and drop "credential" from the list of known mismatches.
