Remove shell command substitution syntax $(date +%Y-%m-%d) from workflow
markdown files that was causing template interpolation to fail. The shell
syntax is not valid in the context/frontmatter section that gets processed
by the template engine.
Fixed files:
- .github/workflows/a3-python-v2.md
- .github/workflows/a3-python.md
- .github/workflows/code-simplifier.md
