Improve informations on community page (napari#482)

# References and relevant issues


# Description

When with @melonora, we have preparing a presentation on EuroScipy we
found that it will be nice to have single code that could be provided to
listeners with links to all our places.

After checking our page, it looks like community page is best for this. 

This PR is improving the content of this page by adding links to missing
places and fixing contributing links.
I have also added headers to improve readability.
