Add confirmation before reset --hard if there are local changes

[abaza738]

Description

When having local changes and performing git reset --hard, it would be beneficial for the developer to warn for local uncommitted changes. I speak with tears in my eyes after I lost all my changes yesterday. I understand that it is my fault, and I am not blaming lazygit.

Proposed solution

A confirmation popup with the option of auto-stashing local changes before performing git reset --hard.

Hello,
I opened a PR about that issue but there seems to not be easily doable because of the way things are done. More explication here #3714
