Show on start doesn't work for the first file opened when opened by telescope

[dane-harnett]

I use https://github.com/nvim-telescope/telescope.nvim for fuzzy file finding.

My nvim-biscuits config is:

require('nvim-biscuits').setup({
    cursor_line_only = true,
})

After opening neovim, I immediately open the fuzzy finder for telescope and select a file (I've tried *.ts and *.tsx and both are affected) - the biscuits are not displayed.

If I open another file using telescope then the biscuits show as expected.

I did some debugging and found that the lang was being determined to be "" when retrieve from ts_parsers.

Happy to provide more info or a video if needed.

I have a suspicion that biscuits is trying to attach to the buffer too early and the treesitter language is not yet determined.

There looks like there is an official way to add modules to treesitter: https://github.com/nvim-treesitter/nvim-treesitter#adding-modules

Which might allow for not doing the BufEnter autocmd technique.

I'll explore this and report back.
