fix default increase_font_size binding config from physical to unicode

[LiamGoodacre]

During d015efc some of the bindings were converted from physical keys to unicode. The binding for font size increase via = was missed. Therefore there was an inconsistency between font size increase and font size decrease. Decreasing with - would be relative to the keyboard layout, whereas increase required the physical = key.

Dedicated discussion: #8743
Original thread on: #8729 (comment)

I've ran zig build run to sanity check the behaviour and all seems well.
Let me know if there's anything else I need to do.

A work-around in the mean time is:

keybind = ctrl+equal=unbind
keybind = ctrl+==increase_font_size:1

Makes sense to me. Let's see what others think

The comment above this implies we're doing this on purpose. I want to understand both sets of problems more before approving this.

I have a related Discussion to this issue. Currently the increase_font_size keybind [src] is using unicode + and the next_tab keybind [src] is using physical_key bracket_right ... Dvorak maps + to bracket_right so these two keybindings are in conflict.

As a Dvorak/Mac user for ~15 years, I agree with this comment on a prior Dvorak discussion, that Ghostty should not be shipping physical keybinds for keys like bracket_right/bracket_left

On a German layout, cmd - decreases the font size, but cmd + does not increase it again. This is broken on nightlies for at least a month now and I would really like a fix. The proposed workaround above also doesn't work on my system.

@dwt, I think this might be related to your issue, as my problem was identical: helix-editor/helix#14624. I originally wrote about it in the comments to this PR but deleted it because I wasn’t sure about the relevance.

One big factor to my confusion with this keybind was that the menu item asserted Cmd + would work —it does not, unless the menu bar is focused. Given that d015efc mentions making bindings ‘match macOS menus,’ perhaps this PR corrects that.

@dontwanttothink Indeed, your comment helps and gives me a workaround for now with this snippet in my Ghostty config:

# Workaround for https://github.com/ghostty-org/ghostty/pull/8759
# Enables cmd+plus to work on german keyboard layouts
keybind=cmd+BracketRight=increase_font_size:1

Sorry, for grabbing your short name on GitHub. The long form of mine is onstensible: DontWannaTell - but I also really like yours. :)

Looking at the code this pull request is trying to change, it only talks about the = key. Does this by any chance cover the + key too, or is this going to be another pull request?
