creating LightOccluder2D polygon makes exclamation mark in scene tree disappear

fixes #21225

This commit fixes an UI bug which leads to a persistent warning in scene tree. Before
this fix the only way to get rid of the warning was to reload the complete scene.

The inspector issue mentioned in #21225 that polygon updates aren't reflected seems to be
fixed in v4.3 and therefore not part of this commit.
