Description

Fixes a markdown fence-nesting bug in skills/aws-well-architected-review/SKILL.md.

The GitHub issue-body template (Step 6) was wrapped in a three-backtick ```markdown fence while itself containing three-backtick ```hcl and ```bash blocks. As a result, the HCL example's closing fence terminated the wrapper early, splitting the template, and the following fence started an unterminated block that swallowed the remaining workflow sections when rendered.

The fix wraps the whole template in a four-backtick fence so the nested three-backtick blocks render intact. Content is otherwise unchanged (2 lines modified).

The same issue was caught by Copilot review on the new Azure counterpart skill (#2448) and fixed there; this PR applies the identical fix to the original AWS skill.
