--version-variable flag alternative to cfg file

When encapsulating release into a reusable ci-cd pipeline component (e.g. CircleCI orbs) it can be nice to automate some config for the project. Currently version_variable must be set in setup.cfg (it seems). It would be great if it can also be passed as a cli flag.

The workaround is to run file manipulations withi the ci-cd job to maipulate setup.cfg as needed.

Something great should be to make python-semantic-release able to work with setup.cfg and pyproject.toml.

This could allow to read/write automatically the new version within the right configuration file. It could allow to completely automated the CD process of a lib.

Something such as:

• Get the new version from vcs history (already exists)
• Bump it and write it in setup.cfg, pyproject.yml or init.py
• Create a new commit for this change, create the new tag on it

At Sewan we will setup this feature and submit a PR from our fork https://github.com/Azraeht/python-semantic-release
