Add a Community section

[ariard]

The LDK project start to be spread across different repositories. Also the type of helpful contributions start to expand (technical writing, infrastructure deployment, product management).

I think we should consider adding a Community section on the website telling about the project history, the modules, their milestones and where to engage with other community participants.

Sounds good @ariard. Here are some things that could be useful to have in this section.

Support - Where to get support to ask code level questions
Team - Bio's for the core team and acknowledgements for regular contributors
Courses - Links to courses teaching people how to use LDK
Showcase - Small example projects
Meetups - Local community events people can attend in person
Conferences - Bigger community efforts with an LDK presence
Articles - Good articles not hosted on the LDK website
Podcasts - Dedicated to lightning and LDK episodes
