I didn't touch the "Using Javascript" section of the README, although it could also use an update. I am not certain what to say about sprockets use in Blacklight 9/main with Rails 7, if it is not supported or what. (I think it is not currently tested in CI, but I'm not sure)
I also reviewed and edited wiki at https://github.com/projectblacklight/blacklight/wiki/How-to-release-a-version
