We're updating PYLS and Pyre to use .pylsp as isolation-prefix: D46599960, D46602539.

We'd like to add these .pylsp to ignore folders to prevent users from having bunch of generated files listed in ISL.

I went through every ".lsp-buck-out" and looked for references of .lsp and added new entries with .pylsp where necessary. There are few code mentions of .lsp-buck that seems relevant that I'll send out another diff for so that I can add the project owners.

Test Plan: reviewbylookingveryhard
