[PHP-WEBMASTER] [web-php] PR #1269: feat(supported-versions): add “Notes” column with upgrade guide links

Pull Request: feat(supported-versions): add “Notes” column with upgrade guide links by PhilDaiguille · Pull Request #1269 · php/web-php · GitHub
Author: PhilDaiguille

This PR adds a “Notes” column to the [Supported Versions](PHP: Supported Versions) page, similar to the one on the [EOL](PHP: Unsupported Branches) page.

Each row now includes a link to the corresponding upgrade guide, improving consistency between the two pages and making it easier for users to find relevant documentation.

Closes #715.
