Support `Tools/` in case-sensitive file systems

[luispadron]

We've been keeping our wrapper in a uppercased Tools/ directory at Tools/bazel. This is because we have existing stuff in Tools/. This works fine for case-insensitive file systems but fails silently on a case-sensitive file system as bazelisk only checks for tools/bazel.

Could we support both/or any casing here?

maybe best solved by https://github.com/bazelbuild/bazelisk/pull/567

[luispadron]

yes that would be perfect thank you @keith. Any idea if theres a desire to merge that from the maintainers? We can keep this open and close it if that merges

haven't heard anything

#567 solves this for us thanks Keith!
