Update README.md

[bryevdv]

Quick edits to remove mybinder info, since the site just finally appears to be fully offline (500 errors even from https://mybinder.org/)

Also removes the bits about bokeh sampledata.

Would probably be nice to collapse old conf sections into a short list with just video and repo tag links since the signup etc info is not useful in an ongoing way. But I'll leave that for others/later.

That's great, thanks a lot! While we are at it, I'd simplify the structure a bit, and remove most of the outdated/irrelevenat SciPy stuff... I'll push a commit in a minute with what I mean!

@bryevdv I made some additional edits - you and @pavithraes can merge (or update) as you like! 😀

I'd suggest keeping the 2024 conf as well, but streamlining to just the video and repo link (i.e. same format as the 2023 section), and maybe a top-level structure like this?

I've pushed an update. Looks scipy 2024 video isn't available yet, so just added a repo tag link. :)
