feat(docs): use mkdocs-click for documenting EEST CLIs

[danceratopz]

🗒️ Description

This PR ensures that our CLI documentation is single source by using:

1. click's built-in help system to document CLIs (for terminal output), and,
2. mkdocs-click, that generates html documentation from the click docstrings.

It also updates the evm_bytes CLI docs to have cleaner click docs and use mkdocs-click for its html docs. This fixes up the previous poor formatting of help strings in the terminal.
