docs: update stale bazel_dep versions in how-to guides

[clanghans]

Summary

• Bump score_docs_as_code 2.0.3 → 4.0.1 in docs/how-to/setup.md
• Bump score_process 1.3.0 → 1.5.3 in docs/how-to/other_modules.rst

The version examples in the how-to guides were significantly out of date. Versions verified against the eclipse-score bazel_registry.
