[PSM Interop] Update packaging to fix requirements-dev.txt (#34142)

Previously black wouldn't install, as it required newer `packaging`
package.

This fixes `pip install -r requirements-dev.txt`. In addition, `black`
in dev dependencies file is changed to `black[d]`, which bundles
`blackd` binary (["black as a
server"](https://black.readthedocs.io/en/stable/usage_and_configuration/black_as_a_server.html)).
