Add Schema.org markup and improve logo accessibility

[amavashev]

Summary

This PR enhances the documentation site's SEO and accessibility by adding structured data markup and improving the logo configuration.

Key Changes

• Added Schema.org JSON-LD markup: Implemented structured data for the Cycles software application to improve search engine understanding and rich snippet generation. The markup includes application metadata, category, description, URL, license information, and pricing details.
• Improved logo accessibility: Updated the logo configuration from a simple string path to an object format that includes an alt text attribute (alt: 'Cycles'), enhancing accessibility for screen readers and users with visual impairments.

Implementation Details

• The JSON-LD script tag is properly formatted and stringified for inclusion in the document head
• The schema follows the standard Schema.org SoftwareApplication type with relevant properties
• The logo change maintains backward compatibility while providing better semantic HTML structure
