Update the app bundle's access and modified times to match the build time on macOS

[Meorge]

(Mostly) closes #102001 .

This adds a step to the bundle-generation script that updates the access and modification times for the macOS Godot editor .app bundle, so that it appears in the filesystem as having been last accessed and modified when the bundle was built, rather than when the original app template was created back in March 2024.

In the orange box here, the executable and app bundle were both just built, while the top two app bundles were built a while time ago. You can see that with this PR, the new app bundle has an accurate "Date Modified" time.

Changing the "Date Created" date appears to be less trivial - I think the easiest way to go about that would be to create the .app directory itself from scratch, then copy all subdirectories from the template bundle into this newly-created directory. If you think that'd be a good idea to pursue, I can update my branch to try to implement that.

This seems to be the easiest way to do it, and since .app bundle always contain only a single Content folder should be as easy as:

It did occur to me last night that the structure of the app bundle, with the sole "Contents" folder, would make it a lot easier to do. I presume we'd want to keep the original shutil.copytree's exclusion of Info.plist, though, like so?

shutil.copytree(templ + "/Contents", app_dir + "/Contents", ignore=shutil.ignore_patterns("Info.plist"))

[Meorge]

I've made the changes now, so that it creates the app directory itself and copies over the Contents directory!

There's probably a more SCons-specific way of doing this, but that's not a dealbreaker
