HTML Document Title on Docs Main Page is "Untitled"

Spring AI Documentation

Description:
I've noticed that the HTML document title on the main page of the documentation is currently set to "Untitled." This can create confusion for users who have multiple tabs open, as it doesn’t provide any identifying information about the project.

Suggested Fix:
Update the HTML <title> tag on the documentation's main page to a more descriptive title, such as "Spring AI Documentation" or "Spring AI Docs."
