feature: show paths relative to lsp root

[fent]

Did you check the docs?

• [X] I have read all the trouble.nvim docs

Is your feature request related to a problem? Please describe.

when opening nvim from outside project folders, it would be useful if the paths shown in the Trouble window would be relative to the lsp root. for example, below i opened nvim from just outside of dotfiles/, a git repo

Describe the solution you'd like

i would like the path to remove dotfiles/ since it's a git repo and my lsp root is dotfiles/. i can see how others may prefer showing a relative path to the pwd, which is what Trouble current does. so maybe this can be an option?

Describe alternatives you've considered

a path_display option as a function for further customization like telescope.nvim has

path_display = function(_, path)
  local tail = require("telescope.utils").path_tail(path)
  return string.format("%s (%s)", tail, path)
end

Additional context

i work in a large codebase with many projects and subprojects. i often open nvim from any directory
