Project List's "Filter Projects" doesn't load first project on Enter key, but "Sort" field does

Godot version

4.0.rc3

System information

macOS 13.1, Apple M1

Issue description

When filtering the list of projects in the Project Manager/List, nothing happens when the user presses Enter while the focus is still on the "Filter Projects" field. But when they switch to the "Sort" field with Tab and then hit Enter, the top-most project is loaded.

(On an aside, there doesn't seem to be any way to focus and navigate the project list itself. Continuously hitting Tab just focuses the "Folder" icons that let me change a project's source folder.)

Steps to reproduce

• Start Godot and wait until you see the list of projects. Ideally, it already has a couple of projects listed :)
• Type something into the autofocused Filter Projects field
• Hit Enter (nothing happens)
• Hit Tab to jump to the "Sort" field
• Hit Enter — now the first project in the list gets opened

Still valid in 4.2-beta1 (with the very appreciated upgrades to the project loader window.)
