move to css animation

[robertIsaac]

it seems that Angular is moving away from animations, since new projects in Angular 19.2 won't have it installed by default and Angular material migrated all of their components to pure css animations and dropped the animations as a dependency
looking at the code it seems there are only 4 animations used in 5 components so it should be feasible to do the same here
of course it's not something urgent since it's not officially deprecated and there isn't an official eof date but it should be planned

@robertIsaac definitely something to explore and research for the future. Thanks for reporting it.
