Change default behaviour of text channel to match only content and not filenames

[Tradeylouish]

The text channel is intended for fuzzy live grepping but its usefulness is limited by the fact that filenames are matched in addition to the content. This means that if you want to search your files for a text string, but that string also appears in one of your filenames, every non-whitespace line of that file will clutter the search results because of the filename match.

This is basically equivalent to this old issue in fzf.vim, where the solution was to pass --delimiter : --nth 4.. options to fzf. The newer fzf-lua seems to be configured to do something similar by default, see "picker options" in their README:

fzf_opts = {
      -- do not include bufnr in fuzzy matching
      -- tiebreak by line no.
      ["--multi"]     = true,
      ["--delimiter"] = "[\t]",
      ["--tabstop"]   = "1",
      ["--tiebreak"]  = "index",
      ["--with-nth"]  = "2..",
      ["--nth"]       = "4..",
    },

I can't see an obvious equivalent solution for television, possibly changes to Nucleo would be required since it is used in place of fzf. But if something can be figured out it would provide a nice usability boost - and help inch Zed and VS Code closer to being configurable into NeoVim haha

this can be solved if this other issue gets implemented #724. You can make the searching scope narrower than the visible one.

For now you could just make

display = "{split:\\::2}"

But you would lose the source file name, but you can see it in the preview window
