Configure requirement ID module via docs()

[AlexanderLanin]

Summary

• add a single module parameter to the public docs() macro
• pass the module consistently to sandboxed and interactive Sphinx builds
• migrate fixtures and documentation away from conf.py lists

Testing

• bazel test //src/extensions/score_metamodel:file_based_tests_id_contains_feature //src:incremental_dirty_build_test //src/extensions/score_metamodel:unit_tests --test_output=errors
• bazel build //src/tests/docs_bzl/scenarios/external_needs/producer:needs_json
• bazel run //src/tests/docs_bzl/scenarios/local_version_mismatch:docs (expected version-mismatch failure)
