putContainerArchive() (and PutContainerArchive) should not have string type hint for inputStream

[mattzuba]

All of the http client message factories that create requests turn bodies into Psr StreamInterface objects if they aren't one already. The string type hint on the this API call forces the dev to read the entire (potentially large) archive into memory as a string before calling the putContainerArchive() method, only for the message factories to turn it into a stream anyway. In 1.24, a string, file resource or StreamInterface object could be passed instead of a string.

With the change in moby/moby#39248 applied to the spec file when generating the PHP code, the result is as expected.

@joelwurtz Is there any chance that this change is backported to docker-php-api? It looks like you currently have no time to maintain docker-php-api... maybe it would make sense to have one (or even more) additional maintainer. WDYT?
