merge_request_approvals_and_blocks.adoc: Hard and Soft Block Clarification
We have two methods of blocking an merge request: GitLab Blocking threads
(soft blocks) and the webhooks '/block' comment (hard blocks).
Trying to classify when one over the other should be used is difficult as
there are many use cases and corner cases. Ultimately a hard block should
be used when a reviewer requires an answer before allowing the MR to
proceed through the process, and a soft block should be used in all other
cases.
Providing scenarios for use seems like it would be a never ending list.
Instead, clarify the use cases for each with INFORMATION sections.
