Only three approvals should be required to merge TCK work

🆕🐥 First Timers Only

This issue is reserved for people who have never contributed to Hedera or any open source project in general.
We know that creating a pull request (PR) is a major barrier for new contributors.
The goal of this issue and all other issues labeled by 'good first issue' is to help you make your first contribution to Hedera.

👾 Description of the issue

Currently, the DevelopmentProcess.md describes that all SDK servers must be complete and tested against the TCK for a particular request type before it can be merged. It has been determined that waiting for all SDKs can result in PRs remaining open for a long time even if they are fully approved. To simplify this and allow PRs to be merged in a more timely manner, only three approvals from SDK leads should be required. This new requirement should be documented.

Proposed Solution:

The requirement of only three approvals should be stated in DevelopmentProcess.md.
