Update support for new lua parser in treesitter

[tonysyu]

It appears that cmp-nvim-ultisnips is running into the same issue described in https://github.com/nvim-treesitter/nvim-treesitter/issues/2295. As described in that issue, updates to the nvim-treesitter lua parser (https://github.com/nvim-treesitter/nvim-treesitter/pull/2272) requires updates to third-party modules. Here's the error output I see when editing a lua file:

Error detected while processing TextChangedI Autocommands for "*":

Uninstalling cmp-nvim-ultisnips resolves the issue on my system.

As some guys mentioned on that issue, can you check if you still have old parser files at ~/.local/share/nvim/site/pack/parser? If so, please delete them. Then try to run :TSUpdate. Does that help?

Edit: Sorry, I just read your last sentence. I don't think we can do anything on cmp-nvim-ultisnips' side to avoid this issue.

My bad, you're right that it has nothing to do with cmp-nvim-ultisnips support for the new Lua parser in Treesitter.

I didn't have a directory called ~/.local/share/nvim/site/pack/parser and :TSUpdate didn't seem to help either, but after removing the entire ~/.local/share/nvim/ directory and restarting, everything seems to be working.

Sorry for the noise!

No worries, glad that everything works now! :)
