Update CDS documentation to cover AOTCache

[mhalbritter]

See spring-projects/spring-framework#34700.

We have some documentation about CDS in the Boot docs, and we should update those to also show examples for Java 24's AOTCache.

Assign to me. I will work on it.

Thanks for the offering, but we'd like to work on documentation issues ourselves. We also have to coordinate with the Framework team if we rename the whole section to AOTcache (which is the new name for CDS from Java 24 onwards).
