No parser for `typescriptreact` language (when treesitter parser name is different from filetype)

[Gelio]

When trying to use nvim-treehopper in a tsx file, I get the following error:

E5108: Error executing lua ...local/share/nvim/runtime/lua/vim/treesitter/language.lua:25: no parser for
 'typescriptreact' language, see :help treesitter-parsers

This seems to be caused by the treesitter parser for the typescriptreact filetype being named tsx. nvim-treehopper tries to use the parser with the same name as the filetype, which is not the case for quite a few filetypes, as shown in nvim-treesitter.

I have decided to report this issue separately from my attempt at solving it (#14), since the progress on that PR has stifled while the issue remains.
