refactor(pages): refine Project pages

* refactor ProjectOverview component to let consumers handle the value
* extract project overview depending on Github to avoid fetching
Github API if the project is not on Github
* wrap dynamic import in a useMemo hook to avoid infinite rerender
* fix table of contents by adding a useMutationObserver hook to refresh
headings tree (without it useHeadingsTree is not retriggered once the
dynamic import is done)
* add Cypress tests
