Description

This PR updates to Dokka 2.0.0, and configures it to eventually be able to publish it.

Changes made

Update Dokka to 2.0.0-Beta.
Add a project description on the homepage of the documentation.
Replace the default All modules page name on the homepage with Pillarbox.
Hide the platform filter in the navigation bar (currently not working, I've opened an issue for that).
Enable Gradle's Configuration Cache.
Add a Module.md file to each module to describe it (it's currently a copy/pates of the first paragraph of the existing Readme.md file of each module).
Configure the source link of each module, so the documentation can link to the source code (currently broken for Android projects 😢).

How-to

To generate the documentation, simply run:

./gradlew :dokkaGenerate

In the output, you should see a link to access the generated documentation:

Generated Dokka HTML publication: http://localhost:63342/Pillarbox/build/dokka/html/index.html
