Update documentation for new kakoune-lsp configuration methods #4698
Description
Is your enhancement request related to a problem? Please describe.
The documentation specifies that configuration for the lsp server should be put in a kak-lsp.toml file, but that method is now considered legacy, and should now be replaced with a toml table in the kakrc file (or an extra file that is sourced) populated by hooks, as described here.
Describe the solution you'd like
I would like to see the new configuration method being documented for hls
Describe alternatives you've considered
The old configuration method still works, and is supported, so there is no emergency, but i can't see it being supported forever, and new configuration features will not be added to it.
