Using the projects plugin in Insiders, I am having the problem that it seems the cache is never updated.

Bug description

Changes to the mkdocs.yml files in project do not get picked up. I am changing the color scheme as an example, see below. It seems the config.pickle file in .cache is not getting updated when a mkdocs.yml file in a project is changed.

Reproduction

9.4.8+insiders.4.43.0-projects-plugin-cache.zip

Steps to reproduce

1. rm -rf .cache
2. mkdocs serve
3. Open subproject in a browser and observe that the project has an indigo palette
4. In another window, edit the project's mkdocs.yml to set the palette to red
5. Make a change to the docs/index.md to see that the browser updates
6. You will see that while the change from (5) shows, the palette is still indigo
7. Restart mkdocs serve
8. Observe that the color scheme still has not changed.
9. Stop mkdocs serve
10. rm -rf .cache
11. Start mkdocs serve
12. Observe that the color scheme has changed now.

Btw. I selected a browser below without thinking and it seems this selection cannot be reset?
