Temporary migration for colorschemes

ts_migrate.lua

-- Run treesitter_migrate() in your init.lua or in a Colorscheme autocmd.
-- See https://www.reddit.com/r/neovim/comments/y5rofg/recent_treesitter_update_borked_highlighting/
-- https://github.com/nvim-treesitter/nvim-treesitter/issues/2293#issuecomment-1279974776

-- the @punctuation.delimiter links to Delimiter (which is new)
-- Also other new upstream highlight values, so the better solution is to go through the following 
-- and properly update/add the highlight for these
-- so like leave @punctuation.delimiter linking to Delimiter and style the new Delimiter

Thanks for this! Great temporary solution until we can fix our themes ❤️

Thank you!!!
