chore: create bcr prs as non-draft so bazel-io processes the bot-created PRs (#3504)

By default, the workflow creates draft PRs. The bazel-io bot ignores
drafts.
Since we can't mark the PR as non-draft ourselves, we then have to wait
for
bcr maintainers to do so.

To fix, create the bcr prs are non-draft. Then we can approve and the
bazel-io
bot will approve and merge the PR.
