chore: improve doc site

[shivasurya]

This pull request includes updates to the documentation and minor code adjustments to improve clarity and functionality. The most important changes include updating the Docker action reference, modifying a quote in the code example, and enhancing the visual layout of the documentation.

Documentation updates:

• docs/src/content/docs/ci.mdx: Updated the Code-Pathfinder SAST Scan GitHub Action to use the main branch instead of a specific fix branch.
• docs/src/content/docs/index.mdx: Modified the quote in the main method example to remove unnecessary escape characters.

Visual layout enhancements:

• docs/src/content/docs/index.mdx: Removed the fixed width from a div element to ensure better responsiveness.
• docs/src/content/docs/index.mdx: Added a new card to the CardGrid to highlight detecting WebView misconfigurations with a link to the relevant blog post.
