chore: Install the CodeSee workflow. (#26315)

This pull request adds the CodeSee workflow to your repository.
This workflow runs a code analysis on each time:

  - a new PR is opened
  - a new commit is pushed to an existing PR
- a PR is merged or a new commit is pushed directly to the default
branch

The analysis enables [code
visibility](https://www.codesee.io/what-is-code-visibility) for your
codebase: generating maps of your codebase, keeping existing maps
up-to-date, and automating code workflows.

Access the CodeSee web app at https://app.codesee.io/ or learn more at
https://docs.codesee.io. If you have any questions, please reach out to
support@codesee.io and we'll be happy to help.
