When there is a patch version added to semver versioning, setuptools.setup(version) will normalize the versioning from `-patch` to `.patch` which is not correct SEMVER versioning. The added feature with setuptools.sic(version) will prevent this from happening.

reverts previous commit for preventing normalization of versioning

chore: add SECURITY.md

This PR migrates from autosynth to [owl bot](https://github.com/googleapis/repo-automation-bots/tree/master/packages/owl-bot).  owl bot will save time for maintainers as it will automatically open PRs when there are updates in [googleapis-gen](https://github.com/googleapis/googleapis-gen/tree/master/google) without requiring maintainers to run `synthtool` to build the client from protos. Additionally, similar to autosynth, PRs will be automatically opened when there are template updates.
