Upgrade CodeSee workflow to version 2

[ghost]

CodeSee is a code visibility platform.

This change updates the CodeSee workflow file to the latest version for security, maintenance, and support improvements (see changelog below).

That workflow file:

• runs CodeSee's code analysis on every PR push and merge
• uploads that analysis to CodeSee.
• It does not transmit your code.

The code analysis is used to generate maps and insights about this codebase.

CodeSee workflow changelog:

• Improved security: Updates permission to be read-only.
• Improved future maintenance: Replaces the body of the workflow with a single github action: codesee-action. This makes it significantly easier for CodeSee to introduce future improvements and fixes without requiring another PR like this.
• Improved Python support: The action now properly supports Python 3.11, and will continue to support new Python versions as they are released.
