Documentation

* docs: give example of multiple build commands (248)

I had a little trouble figuring out how to use a non-setup.py build
command, so I thought it would be helpful to update the docs with an
example of how to do this. ([`65f1ffc`](https://github.com/python-semantic-release/python-semantic-release/commit/65f1ffcc6cac3bf382f4b821ff2be59d04f9f867))

Feature

* feat: bump versions in multiple files (246)

- Add the `version_pattern` setting, which allows version numbers to be
identified using arbitrary regular expressions.
- Refactor the config system to allow non-string data types to be
specified in `pyproject.toml`.
- Multiple files can now be specified by setting `version_variable` or
`version_pattern` to a list in `pyproject.toml`.
