fix(telescope):🐛 worktree list crashing

[GustavEikaas]

This was a weird bug and I want someone to confirm that it also happens on their machines.

When running require('telescope').extensions.git_worktree.git_worktrees() it opens a telescope picker with no entries.
Checking :messages gives the following output

[telescope] [WARN  20:03:04] C:/Users/Gustav/AppData/Local/nvim-data/lazy/telescope.nvim/lua/telescope/pickers.lua:672: Finder failed with msg:  ...lazy/telescope.nvim/lua/telescope/pickers/highlights.lua:33: Invalid 'hl_group': Expected Lua string

This is weird right?

Turns out that this function is the culprit

    local make_display = function(entry)
        return displayer {
            { entry.branch, "TelescopeResultsIdentifier" },
            { utils.transform_path(opts, entry.path) },
            { entry.sha },
        }
    end

Can you spot the bug?

Turns out utils.transform_path has more than one return value, meaning that if you do something like this
local path, arg = utils.transform_path(a,b) returns the following "abc", {} . Given the way this function is inlined into the arguments of the displayer it captures both values instead of only the intended string. Thus giving you the error of Expected Lua string.

Easily fixed by just discarding the second return value

 local make_display = function(entry)
        local path = utils.transform_path(opts, entry.path)
        return displayer {
            { entry.branch, "TelescopeResultsIdentifier" },
            { path },
            { entry.sha },
        }
    end

this must be merged!
independently of you I tried to fix it myself and I fixed it a bit different:
