Temporarily restrict pip version on Windows to avoid failures

[christophebedard]

See ros-tooling/action-ros-ci#719 (comment)

Once pip releases a new version with the fix (pypa/pip#10875), we can revert this.

The Windows jobs probably still won't pass (see ros-tooling/action-ros-ci#719), but if this PR fixes the pip issue (i.e., no The process 'C:\hostedtoolcache\windows\Python\3.7.9\x64\Scripts\pip3.exe' failed with exit code 3221225477 errors) then we can merge it. nevermind
