No enum component example

[MrGVSV]

How can Bevy's documentation be improved?

The ecs_guide example doesn't seem to include an example for enum components.

Since updating an enum component's variant requires a dereference (i.e. *foo = Foo::Bar), it can be confusing to first-time users. This should be included either in that example or a dedicated enum component example.

It would also be worth demonstrating how to pattern match against a mutable enum component as well.

Same is true for updating an entire struct resource at once. i.e. *foo = Foo { bar: 5.0 }
