Fix inverted heading hierarchy in Code of Conduct

Problem

content/code-of-conduct/_index.md (forked from an external template) has its heading levels inverted: H3 elements appear as top-level sections, and H2 elements appear inside what are logically subsections.

Specifically:

• ### Python Ireland Code of Conduct (H3 — should be removed, H1 is set by template)
• ### The Short Version (H3 — should be H2)
• ### The Long Version (H3 — should be H2)
• ### Contact Information (H3 — should be H2)
• ## Attendee Procedure for incident handling (H2 — appears inside a section, should be H3)
• ## Staff Procedure for incident handling (H2 — same issue)

A quality rater checking heading structure would flag this as a structural error.

Additional fix

The document states "As of 2025, the committee consists of..." — update to 2026.

Also verify the Ada Initiative links (referenced in the staff procedure section) — these may be dead links since the geekfeminism.wikia.com migration.

Files to change

• content/code-of-conduct/_index.md

Open content/code-of-conduct/_index.md and inspect the heading hierarchy, the 2026 committee statement, and the Ada Initiative links in the staff procedure section. Compare the headings with the structure listed in the issue, verify whether the links still resolve, and confirm the file has the corrected levels, year, and links.
