chore(release): 8.0.0 [skip ci]

# [8.0.0](v7.0.0...v8.0.0) (2022-01-27)

* Introduce semantic-release ([65e2368](65e2368))

### BREAKING CHANGES

* Every call to marked is isolated now. This makes sure that options from the first call won't influence options from the second call. If you've configured the markdown-loader with two different options, you might observe different behavior now. We also removed Node v8 and Node v10 support and support for older webpack versions. Webpack 5 is required now.
