DOCS Add warning for fetch_initial_posts + more explicit distinction between OTP and from source

See merge request pleroma/pleroma!2262

Add warning to the fetch_initial_posts setting. Now we sometimes have people who enable this without realising the consequences (tons of posts being fetcht as each fetch makes Pleroma discover new users)
I also made a more explicit distinction between OTP and from source installs in the general explanation

Cap the number of requested statuses in timelines to 40 and rate limit them

See merge request pleroma/pleroma!2253

When multiple requests are processed by rate limiter plug at the same
time and the bucket is not yet initialized, both would try to initialize
the bucket resulting in an internal server error.

RateLimiter improvements: runtime configurability, no default limits in tests
