change commit messages and versioning to the semantic way

i prefer the use of [semantic-release](
https://semantic-release.gitbook.io/).
Thats create automaticaly releases [semantic-version](https://semver.org/) based an [conventional commits](https://www.conventionalcommits.org).

So every commit message must have the conventional commit standard:
- `fix(component):` for bugfix
- `feat(component):` for features
- `chore(docs):` for docs
- an `!` in the prefix. e.g. `(component)!:` for breaking change (which create a new major version)
