Docs: Add commit message format checks

[minkyraccoon]

Context

ADR-002 recommended a Comos Cash documentation strategy. This issue is part of an epic to implement that strategy.

Well-formatted commit messages help devs and other users track developments in the repo. It will also allow repo users to search for changes and yield a helpful CHANGELOG for documentation and reporting purposes

Objective

This issue will implement a pre-commit check to ensure that commit messages meet the format as specified by Conventional Commits.

These commit messages will be part of CHANGELOG as part of the release process.
