tox.ini: Add -recommended package factor

[mkoeppe]

This is the same as -standard plus the system packages provided by the _recommended dummy script package, thus suitable for testing doc-pdf.

tox.ini now also allows to pass EXTRA_SAGE_PACKAGES as an environment variable.

Later we can switch the Linux portability workflow to use -recommended instead of -standard.

(split out from #33222)

Depends on #33277
