Support Ctrl+Enter to confirm commit

[KnapSac]

Is your feature request related to a problem? Please describe.
When inside the commit description part of the commit dialog, the default keybind to commit is Alt+Enter. This is unfortunate, because it's also bound to toggle fullscreen in Windows Terminal. I tried to change the keybind by setting keybind.universal.confirmInEditor to <c-enter>, but that is not a supported option.

Describe the solution you'd like
I'd prefer <c-enter> as the default keybind, this is a common UI pattern on the web. I'd also be fine to have it be configurable. I don't know whether the keybind.universal.confirmInEditor setting is used for this, but if so it should probably support <c-enter>.

#1700 might be related, but I believe that it's outdated as Alt+Enter is no longer used to enter newlines in the commit message, which you can now do using Enter itself.

I'd be happy to look into implementing this.

Duplicate of #4397 (and #4502).

This is very non-trivial. You'd first have to implement gdamore/tcell#671, and then add support for this in gocui.

Given the number of users having problems with this (see also #4375 (comment)) I'm wondering if we should change the default keybinding to something like <c-s> for the time being, to at least make it work everywhere. @jesseduffield Any opinion on that?

Wow, I really suck at searching today, my bad!

c-s does seem like a better default in my opinion.

It sounds like we should leave <c-enter> as-is but add an additional keybinding of <c-s>

Ok, added in #4532.
