Update Bazel to 1.1.0 and replace bazelisk by a direct download

This pins the version and avoids the need to redownload the binary
each time the container is recreated.

The .bazelversion file was bazelisk-specific and is no longer needed.

Test Plan:
Rebuilt the container, ran `scripts:launch`.

Modifying the checksum caused to build to fail.
