Fixed formatting issues that emerged after the docx->md translation

…iented language. Specifically:

- CWE-B describes the condition where transient operations are allowed to access and operate on data in a shared microarchitectural structure
- CWE-C describes the condition where a hardware exception causes incorrect/stale data to be forwarded to dependent transient operations
- CWE-D is only a renaming of CWE-C in the previous proposal. CWE-D describes the condition of sharing microarchitectural predictor state
- CWE-E is only a renaming of CWE-D in the previous proposal. CWE-E describes the condition of a microarchitectural predictor causing transient execution
- CWE-A is a catch-all for transient execution, and would be a parent of CWE-[B-E]. Since CWE-B and CWE-C have been refined into specific conditions, I saw no way to avoid introducing a catch-all.

- We removed a CWE that applied exclusively to predictor-based transient execution not involving shared predictor state. We believe that CWE-A suffices to cover these cases.
- Some of that CWE's extended description has been updated and merged into CWE-A.
- There is a placeholder CWE-E that will cover "speculation oracle" weaknesses such as Pacman.
