Disable semantic commits in Renovate

[keeganwitt]

Currently, only Renovate is using semantic commits. We should either merge this and not do semantic commits at all -- or enforce semantic commits across the board (probably with https://github.com/marketplace/semantic-pull-requests and https://commitizen-tools.github.io/commitizen/). It is confusing to have a mix of both.
