feat: migrate to egui 0.24

[SergioRibera]

I updated egui to the latest version and also added the example in the workspace ignore since it is not really necessary to bring it to a library release

These fixes also seem to work for eframe and egui 0.25.0.

Incredible, I had not seen that there is another version, as soon as I have time I will update the PR :D

From what I can tell (though this is my first attempt to do anything with egui), the example code does not work with egui 0.26. With 0.25, then a right-click opens the node finder but if I change to 0.26 then the right-click does nothing. From a quick print statement it seems that cursor_in_editor:

egui_node_graph/egui_node_graph/src/editor_ui.rs

Line 125 in 3068b8c

let mut cursor_in_editor = resp.hovered();

is false for those clicks in 0.26 but true in 0.25. I don't know why. I can't see anything in the changelog that would necessary line up with this: https://github.com/emilk/egui/blob/master/CHANGELOG.md#0260---2024-02-05---text-selection-in-labels

Edit: From what I can tell it doesn't work with 0.26.1 either.

I've tried with 0.26.2 to remove && cursor_in_editor
from this line:

egui_node_graph/egui_node_graph/src/editor_ui.rs

Line 411 in 3068b8c

if mouse.secondary_released() && cursor_in_editor && !cursor_in_finder {

Now right click partially works, but only when you drag and release, while click and release still doesn't work!

What fixed it for me additionally to removing cursor_in_editor is replacing this line:

egui_node_graph/egui_node_graph/src/editor_ui.rs

Line 424 in 3068b8c

if click_on_background || (mouse.any_click() && !cursor_in_editor) {

with

        if mouse.any_pressed() && !cursor_in_finder {
