**PR description:**

This PR adds AWS Skills Profile to Sherlock’s supported sites in data.json. The configuration uses a unique substring (`shareProfileAccepted":false`) for reliable detection of non-existent usernames, addressing the challenge of JavaScript-rendered error messages.
- Site details and detection logic follow Sherlock’s contributing guidelines and Code of Conduct.
- No changes to core logic; only a new site entry.
- Reviewed for schema compliance and duplicate key cleanup as noted.
