chore(java): manually exclude requirements.txt from renovate bot (#860)

Manually brings in changes from https://togithub.com/googleapis/synthtool/pull/1594. [Renovate.json is excluded in owlbot](https://togithub.com/googleapis/java-shared-dependencies/blob/b39e6838c3f3f6ef2b350efe8aec1b622893421a/owlbot.py#L22) so the changes in synthtool couldn't be applied. This is to stop update dep PRs like [this one](https://togithub.com/googleapis/java-shared-dependencies/pull/859) from showing up in the repo.
