Subject: [ruby-core:96267] [Ruby master Bug#11268] Zlib::DataError:	incorrect header check

Issue #11268 has been updated by mame (Yusuke Endoh).


I've changed Net::HTTP to support (raw) deflate correctly.  Now it works correctly.

```
$ ./local/bin/ruby -ropen-uri -e 'URI.open("https://www.hoveround.com")'
```

@nkmrya Thank you for the great investigation.
