I might be picky, but this would actually start downloading the bazel and extracting it. Maybe we should instead use which bazel and Windows-equivalent to avoid expensive download/extract operations.

What do you think if we use 1.x instead?

I put in a specific version (the latest one) to avoid you getting potential bug reports for new behaviour if they release a new version that's broken or similar. They're usually very annoying to chase down. But if you trust upstream's release process enough to not land you in that situation, I can definitely change it. :)
