## Description
<!-- Describe the big picture of your changes to communicate to the
maintainers
why we should accept this pull request. -->
This change makes it possible to configure other formatters for
filetypes supported by the prettier extra, for instance
```js
return {
{
"stevearc/conform.nvim",
opts = {
formatters_by_ft = {
css = { "stylelint" },
},
},
},
}
```
Currently the prettier extra overwrites any existing `formatters_by_ft`
for the filetypes it supports. I've changed it to use `table.insert`
[like the sql extra
does](75750be1c0/lua/lazyvim/plugins/extras/lang/sql.lua (L148-L149)).
