This commit introduces a JSON schema for the SQL course on the roadmap.sh platform, enhancing the metadata associated with the course. The changes are primarily made in two files: BaseLayout.astro and sql.astro. In BaseLayout.astro, the script responsible for rendering JSON-LD data is modified to directly utilize the jsonLd array, ensuring that multiple JSON-LD objects can be handled correctly.

In sql.astro, a comprehensive JSON-LD structure is added, detailing various aspects of the SQL course, including its name, description, provider, publisher, pricing, and educational prerequisites. The schema also includes aggregate ratings and reviews from users, which can enhance search engine visibility and improve the course's online presence. This structured data aims to provide better context to search engines and improve the overall user experience for prospective learners.
