The effort documentation is outdated

[Galaxy4594]

Encode_effort.md is not accurate anymore with the release of libjxl 0.10.x. Outside of the "brute force" effort now being 11, does VarDCT e10 do anything special? Or does it simply do more Butteraugli iterations? What about e9 vs e10 lossless? I think it should also mention which efforts use the new streaming mode by default in 0.10.x. Jon Sneyers in the JXL discord mentioned that e10 disables streaming by default.

I should also mention that for benchmarking.md, "glacier" is equivalent to e10, so what is e11? And the target bitrate command -r is depreciated.
