Feature request: `commitizen` should support revert commits

I know that a similar request was discussed before, however angular does contemplate revert commits.

As a minimum, cz check should accept commit messages beginning with revert:, otherwise when it is configured as a pre-commit hook it does not allow revert commits.

Moreover, IMHO a cz revert command should be added, accepting the <commit> to revert. It should run git revert <commit>, including in the message body: This reverts commit <hash>. as per angular instructions. See information on git revert.

For examples of revert commit messages, see for instance standard-version and conventional-changelog commit logs.

Notice that both commitlint and gitlint support revert commits.

This issue is raised more than one time (I had the same question when I first use commizen as well.) Maybe we could consider adding it to FAQ in documentation?

I now noticed the following definition of the schema_pattern function in conventional_commits.py:

def schema_pattern(self) -> str:
    PATTERN = (
        r"(build|ci|docs|feat|fix|perf|refactor|style|test|chore|revert|bump)"
        r"(\(\S+\))?:\s.*"
    )
    return PATTERN

So it includes both revert and chore.
