Meaning the testing installer?  Upgrading a existing installs to testing is not
supported.  Install fresh or keep using the old repo - which also has 3.18 (but
without all the new dependencies and therefore w/o point cloud support).

The default python in testing is 3.9 and gdal_calc from testing expects that,
but the default python in the old repo is python 2.7, which is apparently what
you have.  So it looks like you tried to upgrade your existing install, which as
said will not work.
