Deprecations messages in symfony 5.4

[Spawnrad]

Describe the bug

Lot of deprecation messages when using this SDK with Symfony 5.4

Expected Behavior

No deprecation message

Current Behavior

User Deprecated: Method "Iterator::key()" might add "mixed" as a native return type declaration in the future. Do the same in implementation "Aws\ResultPaginator" now to avoid errors or add an explicit @return annotation to suppress this message.
User Deprecated: Method "Iterator::next()" might add "void" as a native return type declaration in the future. Do the same in implementation "Aws\ResultPaginator" now to avoid errors or add an explicit @return annotation to suppress this message.
User Deprecated: Method "Iterator::valid()" might add "bool" as a native return type declaration in the future. Do the same in implementation "Aws\ResultPaginator" now to avoid errors or add an explicit @return annotation to suppress this message.
User Deprecated: Method "Iterator::rewind()" might add "void" as a native return type declaration in the future. Do the same in implementation "Aws\ResultPaginator" now to avoid errors or add an explicit @return annotation to suppress this message.

These warnings come from Aws\ResultPaginator and the trivial fix is to add typing to phpdoc for the methods (like it was done here already: #2434)
