Display the Minus hotkey label correctly

[NoryGit]

Description of the proposed changes

The 'Minus' key was missing from the signs table in hotkeylabels.lua, causing the raw string "Minus" to be used. Since hotkey labels only support strings up to 3 characters, this triggered a Not showing label for keybind Minus due to length warning and prevented the label from showing.

Mapping "Minus" to "-" in the signs table resolves the issue.

Poem

A minus key hopped into view,
With dashes now shiny and new,
The rabbit did sing, with a hop and a swing,
For mappings that sparkle in blue! 🐰✨
