chore(renovate): configure to use chore() commit type for all PRs
chore(renovate): configure to use chore() commit type for all PRs

This is necessary in order to keep the package.json files in the
examples directory up-to-date without triggering an unnecessary npm
release when the examples' dependencies are updated (the examples are
.npmignored, so this would result in an "empty" re-release.) Since
atom-ts-transpiler only has devDependencies and peerDependencies, we can
correct this issue by simply forcing Renovate to always use the "chore"
commit type.
