Added markdown version of pretrained_saes.yaml

[skunnavakkam]

Description

This adds a markdown file that converts the yaml file in pretrained_saes.yaml to a nice table in the docs. This was referenced in index.md

No code was changed.

Was this generated via a script? If so it would be great to commit that script as well, and maybe add it as a target in Makefile so we can run something like make update-pretrained-saes-docs to keep this up-to-date in the future as more SAEs are added to the YAML

I did the conversion with Claude and then combed over it to make sure no errors, but I think that scripting shouldn't be too hard and I don't mind implementing

Scripting would be good. I'd prefer not to quote those L0's / variance explained since they were on a random piece of text for a stop gap testing solution. Will set up benchmarking soon (after I accept Josh's PR) and will report the stats coming out of there. Thanks for this!

I've made a script that does this now. https://jbloomaus.github.io/SAELens/sae_table/

Would love any feedback on the page / suggestions! My current vibe is:

• Maybe one monolithic table would be nicer?
• We should probably add comments for each SAE to explain which to use.
• Once we have SAE Benchmarking running across all of these we should have a toggle for "show me config in detail" vs "show me the summary stats" in detail.
