timestampFormat was not supported in shapes definitions
timestampFormat is supported in service metadata but not used anywhere (neither botocore nor amazonka annexes) (it was quickly checked by turning it into a Maybe Void; no parse error was triggered)
This PR adds support for reading it in shape definition and removes support from reading it from service metadata.
