tools/docker: Install bazel from the official bazel repo

[avagin]

The debian repo contains an old version and it can't build gVisor:
external/rules_pkg/private/pkg_files.bzl:315:12: name 'json' is not defined

We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that by leaving a comment that contains only @googlebot I consent. in this pull request.

Note to project maintainer: There may be cases where the author cannot leave a comment, or the comment is not properly detected as consent. In those cases, you can manually confirm consent of the commit author(s), and set the cla label to yes (if enabled on your project).

Were you able to build the container? It worked initially, but then I remember there were some issues (unrelated to bazel, just broken debian).

I can build it on my workstation without any issues:

That's good!
The change looks good to me. @a-nogikh will deploy it next week. Here are the instructions:

I've built and uploaded the new docker image.
