Make animate_targets run before inherit_weights (#16981)

# Objective

ensure that `animate_targets` runs **before**
`bevy_render::mesh::inherit_weights` to address the one-frame delay

Fixes #16554 

## Solution

switch ordering constraints from `after` to `before`

## Testing

ran bevy_animation tests and the animated_fox example on MacOS
