Git commit amend support

[AntonKrug]

Is your feature request related to a problem? Please describe.
I would like to be easily to do commit amend

Describe the solution you'd like
Maybe Shift + C to have dialog similar to a commit dialog, but pre-populated with last/previous commit message

Describe alternatives you've considered
right now when i need to do this i run my bash alias command to fetch previous log message and have it ready for me to paste back the original and do slight modifications or keep the original message but add more files into the same commit without changing the message

[extrawurst]

once the commit popup is open there should be a Amend option. Is that what you had in mind?

I think the request is to support amending any commit like described here #2584 , Lazygit has quite nice ergonomics around amending/squasing/moving any commit in the history.
