[DEMO] Add yourself to the contributor wall #62

This is a demonstration issue. It is deliberately tiny, so it can be
done start to finish in a couple of minutes. If you are brand new, these are
the ones to start with.

Context

The contributor wall currently has one entry. Adding yourself is the gentlest possible first pull request — one small new file, no code, and your name appears on the live site within a minute of merging.

What to change

Files: contributors/<your-github-username>.json (a new file)

Requirements:

• Copy contributors/_TEMPLATE.json to contributors/<your-username>.json
• Use your exact GitHub username as the filename — lower case, no spaces
• Fill in name, github, and optionally quote and interests
• Do not edit contributors/index.json — a robot rebuilds that after merge
• Do not touch anybody else's file

Acceptance criteria

• A new file exists at contributors/<your-username>.json
• python3 scripts/build_contributors.py --check passes
• Only one file was added and nothing else changed

How to verify locally

python3 scripts/build_contributors.py --check
python3 -m http.server 8000   # then open the wall page

How long this takes

Two minutes. No code, no prior knowledge. This is the one to try first.

Stuck at any point? Comment here saying what you have tried and where it stopped working — that is not an admission of failure, it is how we find out the instructions were unclear.
