Add `--keep_going` to make Bazel support more robust

[Silic0nS0ldier]

Resolves #287

With the changes in this PR, the language server works much better in the Bazel repository (provided bazel build //src:bazel-dev has been run, otherwise the external dependencies aren't in the expected places).

Also included in this PR;

• Noted that temporary files for Bazel command output are not cleaned up after use.
• Pinned Bazel examples (used in tests) to version 4.2.4, which appears to be the version expected. Without this tests will fail due to bazelisk (from Github actions runners) will pull in the latest stable release (7.2.x at time of writing).
