Adding the show_symlink option to finder

[aadi58002]

Addresses the issue #300

And also the reopen issue for #323 ( which was closed by mistake )

I think we're on the right track.
Besides the changes I mentioned, we also need to tackle the <cr> behavior when show_symlinks = true and follow_symlinks = false.

Right now, the open_dir action already calls fs_realpath so it follows symlinks regardless of the follow_symlinks option. I think this can be considered a bug.
Probably want to take that out. We can dictate which path (real or symlink) <cr> will act on here:

telescope-file-browser.nvim/lua/telescope/_extensions/file_browser/make_entry.lua

Lines 222 to 224 in d7c4533

	if k == "path" then
	return t.value
	end

by setting this to realpath if follow_symlinks = true or keep it t.value.

Also CI is failing. I think you just need to run stylua.
