Subject: [PATCH] fix: change config for treesitter

Both `install()` and `get_available()` are nil which causes the error
while spawning nvim and make the treesitter not working.

Replacing the custom `FileType` autocmd and manual parser attachment
logic with the standard `nvim-treesitter.configs` setup function
seems to work fine.
