sdist is missing dump_all_version_info.py

[mtelka]

Describe the incorrect behavior you saw
The tox.ini file as included in sdist at PyPI refers to dump_all_version_info.py, but dump_all_version_info.py is not included in the sdist. https://github.com/twisted/twisted/blob/twisted-22.10.0/tox.ini#L91

Describe how to cause this behavior

Any attempt to run tox fails with:

$(BLDDIR)/Twisted-22.10.0/.tox/lint/bin/python: can't open file '$(BLDDIR)/Twisted-22.10.0/admin/dump_all_version_info.py': [Errno 2] No such file or directory

Describe the correct behavior you'd like to see
Either the dump_all_version_info.py should be added to sdist, or tox.ini should not use it.
