I added a new example into CI and got the following error:

The number of tasks in one config file is limited to 80!

This is because of https://github.com/bazelbuild/continuous-integration/blob/master/buildkite/bazelci.py#L650

A few observations about our ci.

1. We have a single file, I am not a buildkite expert, but I wonder if we can break it up into multiple files.
2. We are testing across multiple Linux platforms: Debian and Ubuntu. I am wondering if we can drop one of those.
3. We are running tests for both bzlmod and WORKSPACE files (not sure we can do anything here). Maybe combine those into a single run that happens in the same task?
4. We have separate runs for each folder under "tests". Can we combine these at all?

The TLDR; is that we have a lot of tests in one file. I love tests, but we need to see if we can break them into different files or prune the number of tests. I assume that we are going to get more and more tests for both bzlmod and WORKSPACE files.
