### System information

### Issue description

In Godot 3, Polygon2D UV editor followed the texture's filer parameters, making it easy to edit polygons for pixelart sprites.

However, the same doesn't happen in Godot 4, where the expected result is the `texture_filter` parameter of `Polygon2D` node being respected. Instead, a linear filter is used. Project defaults are ignored, too.

### Possible fix
It seems to be fixable by adding `uv_edit_draw->set_texture_filter(node->get_texture_filter_in_tree());` to `Polygon2DEditor::_menu_option` function in `editor/plugins/polygon_2d_editor_plugin.cpp.` That way, the window's texture filter is set accordingly every time a polygon is being edited. However, I'm not experienced enough in C++ to consider this fix safe and clean. 

I used `get_texture_filter_in_tree()` instead of `get_texture_filter` to account for `TEXTURE_FILTER_PARENT_NODE`. 

### Steps to reproduce

1. Add a Polygon2D node and assign a pixelart texture to it. This lock can be used as a reference.

2. Set the node's Texture filter to "Nearest".
3. Open the UV editor of that node and behold the blurred version of the sprite.
