Summary

Fix the YAML syntax error in the weekly roundup workflow.

Problem

.github/workflows/generate_my_web_this_week.yml contains a run: | block with an embedded Python heredoc. The heredoc body is flush-left, which breaks YAML parsing and makes GitHub reject the workflow around line 39.

Decision

Re-indent the heredoc body and terminator so they remain inside the YAML block scalar while preserving the shell behavior of the workflow step.

Expected Outcome

• GitHub accepts the workflow file.
• The Resolve Target Sunday step still writes TARGET_DATE into $GITHUB_ENV.
• Workflow behavior stays the same aside from becoming valid YAML again.
