Fixes #2891 (potentially)

After I saw that issue after a long a time, I decided to take a deeper dive to how lazyfile works.

Unfortunately, with my lack of programming experience, I could only understand some things on the surface, so I ended up doing some vim.print to have some visual hints. I then noticed that filetypedetect was given back from Event.get_augroups(event.event) and included in the skips table, which is later excluded in Event.trigger.

My assumption was that due to filetypedetect being skipped, the filetypes added in extras.util.dot could not be detected in LazyFile event when Neovim was invoked with file arguments, as also stated in the aforementioned issue.

So, I just tried to exclude filetypedetect from being added to skips table and when I tested it locally it worked when invoking Neovim with file arguments.

I would love some input from the maintainer, as the steps I followed were mostly based on logical deductions, rather having in-depth knowledge of what's actually going on in the lazyfile function and the maintainer is obviously the one most intrinsically acquainted with LazyVim codebase and obviously there might be a more correct way to do it.
