fix frontpage for alpine documentation wiki
The wiki was originally the main page for www.alpinelinux.org, ie an entry point to find git, docs, downloads, mailing lists etc. The navigation still reflects this. Now, since we have another site for that, the wiki frontpage should make it clear that this is a documentation site. The main purpose of the frontpage here is to help user find the documentation he is looking for.
To do so I suggest we remove everything thats not documentation related from the navigation bar, have 3 big icons on front page helping users find the 3 most common things users are looking for. For example “install documtentation”, “Users handbook/manual/documentation” and “Developers handbook/manual/docuementation” or similar.
