Updated SkeletonProfile's main and property descriptions

Updated SkeletonProfile's main and property descriptions
-Description now has note about read only quality
-"bone_size" and "group_size" property descriptions have been added and clarified.
-Property descriptions refer to BoneMap page instead of [code]bone_map[/code] from [Retargeting 3d skeletons](https://docs.godotengine.org/en/latest/tutorials/assets_pipeline/retargeting_3d_skeletons.html#bone-map).
-all property descriptions now do not have any Notes to split them
-TokageItLab clarifies property descriptions to highlight their use

+		[b]Note:[/b] These parameters need to be set only when creating a custom profile. In [SkeletonProfileHumanoid], they are defined internally as read-only values.
