This reverts commit cb378edc.

Offline pub assumes that the pub cache contains all needed packages.  Running
"flutter create" in online mode first will ensure that the pub cache is populated.

Fixes https://github.com/flutter/flutter/issues/89759

* Use `dart __deprecated_pub` instead of `pub` to invoke pub from tools

The top level `pub` commmand has been deprecated and will print
a message. It is however implemented via the __deprecated_pub command
that prints no message.
