Update the protobuf version to 4.X

[sandeepvinayak]

The current version of protobuf being used in tablestore is 2.4.1 which causes issues with conflicts in the consumer service if it has it's own protobuf-java dependency.
Even though the workaround is provided here https://help.aliyun.com/zh/tablestore/support/what-do-i-do-if-pb-library-conflicts-occur-when-i-use-tablestore-sdk-for-java for maven, this workaround doesn't work with other build framekworks such as bazel.
Secondly, 2.4.1 was released back in 2013 and has many security vulnerabilities.

Please upgrade the protobuf-java to 4.x
