Show file defining a mapping for Telescope keymaps

[MarcelRobitaille]

Is your feature request related to a problem? Please describe.
It would be great if Telescope keymaps could show the file defining a particular keymap. Right now, I am having the problem that something (presumably one of my plugins) is defining a keymap that is interfering with one of my custom keymaps. The name of this mapping is not similar to the names or functionality of any of my plugins, so I have no clue where it comes from.

Describe the solution you'd like
Telescope keymaps shows a third column showing the file name and line number of each mapping.

I looked through internal.keymaps, which pointed me to vim.api.nvim_get_keymap and help maparg, which does not seem to provide this information. So I'm not sure how easy/possible this would be.

Turns out I can just do verbose map <mapping>. Still would be a nice feature though in my opinion.

I also think this would be nice to have

Me too!

Any progress on that since?

I think it's unlikely this will happen without some api to get this info that's better than calling verbose map on each keymapping and parsing out the definition path.
