gptel-anthropic: Update models constant (#483)

gptel-anthropic.el (gptel--anthropic-models): Replace sources with
link to a comprehensive comparison table.  Reorder models to
reflect the order in that table.  Slightly tweak description of
claude-3-5-sonnet-20240620 to make it clear it is an earlier
version.
