Hello, sip6 maintainers.

I've noticed that sip6 in Fedora ELN Requires and BuildRequires python3-toml.

The library is used in:

sipbuild/pyproject.py
25:import toml

sipbuild/bindings_configuration.py
25:import toml

Please work with SIP upstream to migrate to tomlllib (tomli) and tomli-w.

See https://fedoraproject.org/wiki/Changes/DeprecatePythonToml and https://tiny.distro.builders/config-unwanted--sst_cs_apps-unwanted-python3-eln.html for why is python3-toml not desired.

I can help with the patch itself, but I am not very familiar with contributing to riverbank's mercurial.

Thanks.

Acceptance Criteria:
Either sip6 is not in RHEL 10 beta or it is, but it no longer depends on python3-toml on runtime or buildtime.
