Update protoc install action in push_release.yml to match tests

[jamie256]

Description

Follow up from yanked release 0.7.3, this should resolve that issue where we pulled latest protoc to build the released wheels which then referenced the new builder type in protobuf which is not backwards compatible with older protobuf.

This now matches our python ci config.
