ci: Install wheel before installing any other python packages.

GHA is broken due to update to pip>=22.0.  This happens because now it
stops backtracking packages on build failure making it impossible to
find working combination of versions.

We're not able to build 'hacking', because 'wheel' is not installed
at that point in time.  Installing it separately to fix the issue,
so pip can find compatible versions of packages by backtracking.

Unfortunately, new version of backtracking leads to installation of
incompatible versions of flake8 and hacking.  Presumably because
current versions of hacking are not compatible with flake8>=4.0
and very old hacking-0.5.4 for some reason is considered suitable
while resolving dependencies.  So, we end up with flake8-4.0.1 and
hacking-0.5.4 installed.  And that doesn't work.  Limiting the version
of hacking to >=3.0 to have flake8-3.9.2 and hacking-3.0.0 installed
during backtracking.
