List of treesitter grammars to disable highlighting for.
This option can be either a list, in which case it will be
converted to a Lua table containing grammars to disable
highlighting for, or a string containing a **lua function**
that will be read as is.
::: {.warning}
A comma will be added at the end of your function, so you
do not need to add it yourself. Doing so will cause in
syntax errors within your Neovim configuration.
