[animations] `fesm2015` entry is actually not ES2015 compatible due to `Object.fromEntries` usage

See original GitHub issue

Which @angular/* package(s) are the source of the bug?

animations

Is this a regression?

No

Description

I imagine fesm2015 should be ES2015 fully compatible, but Object.fromEntries is used in @angular/animations which is actually an ES2019 feature.

Please provide a link to a minimal reproduction of the bug

https://unpkg.com/browse/@angular/animations@14.1.3/fesm2015/browser.mjs

Please provide the exception or error you saw

Correct, only the latest 2 versions of Chrome are officially supported. The current version of Chrome is 105, so 65 is way old at this point.

@JoostK I just had the issue too on Chrome v65, but I guess it’s not officially supported anymore by Angular (I didn’t check).
