This patch removes hard-coded Python path in karma.conf.js
to fix the npm jobs because now these npm jobs run on
debian-bullseye and py38 are not available there.
It also update tox.ini for tox4 to fix the CI for the following:
- Drop "skipsdist = True".
When skipsdist=True is specified, a target application is not
installed into a tox env, but there seems no reason to do so.
In various other OpenStack projects, a target applicatin needs
to be installed into a tox vnev, for example, in docs and/or
linter jobs and it causes failures with tox4. So dropping it
would avoid potential future failures.
- Use comma to have multiple values in a single line for passenv
variable in ``tox.ini`` file.
