Documentation: Update copyright year and fix broken internal links

[thechillbasu]

Describe the documentation issue:

Several documentation issues need to be addressed in the landscape repository:

1. Copyright year in footer configuration is showing 2025 instead of 2026
2. Broken anchor link in CONTRIBUTING.md pointing to non-existent section
3. Incorrect license links in both CONTRIBUTING.md and README.md

Location:

Copyright Year:

• File: settings.yml
• Line: 142
• Current: "Copyright © 2025 JSON Schema. All rights reserved."
• Expected: "Copyright © 2026 JSON Schema. All rights reserved."

Broken Anchor Link:

• File: CONTRIBUTING.md
• Line: 29
• Current: Links to #improving-the-landscape- (non-existent section)
• Expected: Should link to #improving-the-docs-

License Links:

• File: CONTRIBUTING.md

• Line: 86

• Current: Links to website repo's CONTRIBUTING.md

• Expected: Should link to README license section

• File: README.md

• Line: 54

• Current: Links to website repo's CONTRIBUTING.md

• Expected: Should link to main LICENSE file

Steps To Reproduce:

1. Go to https://landscape.json-schema.org/
2. Scroll to the bottom of the page
3. Look at the footer copyright text
4. See it displays "Copyright © 2025 JSON Schema. All rights reserved."
5. Open CONTRIBUTING.md and click "Improving the Landscape" link in table of contents - it doesn't work
6. Check license links in both CONTRIBUTING.md and README.md - they point to incorrect locations

Expected Behaviour:

All documentation should be accurate and up-to-date with working internal links and correct external references:

• Footer should display "Copyright © 2026 JSON Schema. All rights reserved."
• All internal anchor links should work correctly
• License links should point to the correct files
