Upgrade tox (#3624)

* Upgrade tox

* Remove tox-factor

* Bump tox cache

* Remove exporter-jaeger from matrix

These tests were removed in 2a8d4ed,
but tox-factor just ignored the problem, but tox 4 fails because the env
does not exist.

* Ignore py37 getting-started

The py37 env was removed in 4a2cb86
and now tox 4 fails instead of ignore it like tox-factor.

* Ignore pypy3 for some packages

* Github actions exclude does not accept arrays

* Contrib tests still running on tox 3

* Revert "Contrib tests still running on tox 3"

This reverts commit fdcd75d.

* Update contrib SHA

* Remove excludes

* Revert "Remove excludes"

This reverts commit 1cf7b42.

* WIP

* More WIP
