git-submodule.txt: fix AsciiDoc formatting error

In b57e8119e6 (submodule: teach set-branch subcommand, 2019-02-08), the
`set-branch` subcommand was added for submodules. When the documentation
was written, the syntax for a "index term" in AsciiDoc was
accidentally used. This caused the documentation to be rendered as

	set-branch -d|--default)|(-b|--branch <branch> [--] <path>

instead of

	set-branch ((-d|--default)|(-b|--branch <branch>)) [--] <path>

In addition to this, the original documentation was possibly confusing
as it made it seem as if the `-b` option didn't accept a `<branch>`
argument.

Break `--default` and `--branch` into their own separate invocations to
make it obvious that these options are mutually exclusive. Also, this
removes the surrounding parentheses so that the "index term" syntax is
not triggered.
