Correct Super Bot Fight Getting Started (for Pro?)

### Existing documentation URL(s)

- https://developers.cloudflare.com/bots/get-started/super-bot-fight-mode

### What changes are you suggesting?

rewrite "To start using Super Bot Fight Mode:". With a pro subscription, there is no on/off toggle for super bot fight mode. (Maybe business or enterprise have one, but I doubt it.)

The actual pro-level instruction to begin using Super Bot Fight is probably
Change "Definitely automated traffic" from "Allow" to "Managed Challenge". (Leave "Verified bots" as "Allow" to, for instance, permit GoogleBot crawls.)

managed challenge should link to https://developers.cloudflare.com/cloudflare-challenges/challenge-types/challenge-pages/#managed-challenges???
