Add support for markid plugin

[danymat]

Hello, it's been a while ! I hope you're doing good

I propose this small snippet to add to the plugin dir (plugin: https://github.com/David-Kunz/markid)

                local function palette()
                    local p = require("rose-pine.palette")
                    return { p.foam, p.rose, p.iris }
                end

                require("nvim-treesitter.configs").setup({
                    markid = {
                        -- enable = true, (will not be in the PR, but necessary for test)
                        colors = palette(),
                    },
                })

If you're okay and you like it, i can open a PR to implement the idea
