Moves ADRs into project and adds ADR's pages

This commit moves the ADR folder into the project, so that the project
can dynamically create pages for them.

New ADRs still can be added just as they were added before: by creating
markdown files inside the ADR folder.

The project automatically renders HTML pages for the ADRs and:

- The sidebar automatically creates buttons for each ADR;
- Mermaid plugin was added to display diagrams inside ADRs;
- Code styling was implemented inside ADR pages.
