FAQ: some of the prose seems out-of-date / misleading

• Copyedits are needed: e.g., write "see, XYZ" rather than "see here".
• E.g., see https://github.com/grpc/grpc.io/pull/499#discussion_r518208643 which refers to this content:

  What is the latest gRPC Version?

  The latest release tag is {{< param grpc_vers.core >}}.

From https://github.com/grpc/grpc.io/pull/499#discussion_r518440439:

There's always been multiple gRPC languages with their own releases. Go and Java went public the same day C core did. I do not disagree with your confusion at all, but I'll note for minor versions (like v1.33), the languages stay someone close. I wouldn't mind it being deleted. There's much better places to find this information. We could instead link to the /releases page of github for multiple repositories if we really felt the need to have it.
