Review and reorder Tools section #243

Currently a lot of tools are listed in https://robotframework.org/?tab=tools#resources
They are ordered by their GitHub Stars.

But

• Some of them seem irrelevant, since the Robot Framework Language Server was introduced
• Some important tools like the LSP for VS Code and PyCharm (which seem VERY important to me) are listed at the bottom while older ones (like RED) are listed at the top

I propose to

• Review each tool entry if it really makes sense and is needed
• Pin some important tools permanently to the top (independent of their GitHub Stars)

This will help new testers to start with the proper toolset from the beginning
