ci: bump coverage workflow refs for --build_tests_only fix

[dcalavrezo-qorix]

Bumps the cpp-coverage.yml / rust-coverage.yml refs to cicd-workflows 4c20f0d9 (eclipse-score/cicd-workflows#165, fixes eclipse-score/cicd-workflows#164).

Why: the coverage workflows ran bazel coverage/bazel test without --build_tests_only, so test language/tag filters only affected which tests run — wildcard patterns still built filtered-out tests. That builds the Miri test targets, whose Miri-sysroot compiles fail under coverage instrumentation (error[E0463]: can't find crate for 'profiler_builtins') once score_toolchains_rust ≥ 0.9.2 enables Rust coverage — this is what breaks the C++ Coverage job on #369.

Verification: reproduced locally on the #369 toolchain bump — without the fix the coverage invocation aborts (16/19 tests); with --build_tests_only, exit 0 and 19/19 tests pass. The same bump has also been pushed onto #369 directly to re-run its CI.

Merging this first means #369 (and any future toolchain bumps) stay green.

Think the comment with the version doesn't make sense to keep. Same thing with the on line 36
