change-domain-binding-of-product-key.md: H1 doesn't match index link text or frontmatter title

[lyzhang0113]

Found while reviewing docs in PR #30 — left as-is there since the repo has a mix of styles here and rewriting risked just creating a different mismatch.

File: barcode-reader/web/configuration/change-domain-binding-of-product-key.md

• H1: "How to Secure Your License Key by Managing Domain Binding?"
• configuration/index.md link text: "How to change domain binding of product key?"
• Frontmatter title: (matches the index text, not the H1)

Worth deciding which phrasing should be canonical and aligning the other two to match.

Fixed in commit c8c07e0 on faq-docs-quality-pass (PR #30). Unified everything around "How to change the domain binding of a product key?" — it matches the filename and the actual step-by-step content, so I applied it to the H1, frontmatter title/description, and both index.md link texts that point to this page (web/configuration/index.md and web/index.md). The existing filename already matched this phrasing, so no rename was needed.
