arch_release_promotion/argparse.py:
Change `ArgParseFactory.__init__()` to allow overriding the program name
add a `-V`/`--version` argument which may be used to trigger showing the
version of the program.
Change `ArgParseFactory.promote()` to replace the required `name`
argument with the optional `-p`/`--project` argument and adding an
optional `-r`/`--release` argument which may be used to override the
release version to promote. Print program name and version information
and exit early if version information is requested.

tests/test_argparse.py:
Change tests to accomodate for the new optional arguments.

arch_release_promotion/cli.py:
Replace the use of `args.name` with `args.project`.
