Idea: Add section for community client libraries

[katarinasupe]

We added links to 2 community client libraries within current docs. We now have a new implementation in the community for Swift. It might be better to have a separate section for community client libraries on the main page. That would highlight the community members as well as help us better track the work that the community does. Here are the community client libraries we are aware of:

• Swift - https://github.com/ptliddle/SwiftMemgraphClient
• C# OGM - https://github.com/circles-arrows/blueprint41
• PHP - https://github.com/stefanak-michal/memgraph-bolt-wrapper

Also, there is a community Cypher GUI.

Recently, the community was interested in writing their own clients for Memgraph in Julia, Go (OGM) and OCaml. The above would go hand in hand with a potential client contribution guide from DX.
