Output mouse bindings in wezterm show-keys --lua

[hexchain]

Is your feature request related to a problem? Please describe.
I was trying to remove some default mouse bindings (by trying to dump them, removing the unwanted ones, and turning off default assignments), but realized that show-keys --lua, unlike show-keys, does not print mouse bindings.

Describe the solution you'd like
Unless there is a better way to remove a few default bindings, I would like show-keys --lua to also print out mouse bindings.

Describe alternatives you've considered
N/A

Hi @wez, thanks for your great creation, also faced this issue, can I know is this intentional, or it's a bug?
