Update CharFXTransform: explain "relative index"/"absolute index" (previously identical)

Browse Source 
Confusingly, these two properties had identical descriptions even though they measure different things.

"relative_index" measures character count from the custom effect's bbcode opening tag.
"absolute_index" measures character count from the start of the bbcode text that includes the custom effect.

See the code author's own explanation here: https://github.com/godotengine/godot/pull/23658

NOTE: Doco for CharFXTransform.xml has changed significantly in 4.0, where terminology has changed to "glyph".  Therefore, proposing this change for 3.x branch only.
(cherry picked from commit 89cebd79e8)
