feat: Add Blog Post: DVLA @ AI Engineering Lab Hackathon

[piprees]

@Simon-Evs and I have reviewed the guidelines and this blog post has been reviewed by all those who have contributed quotes, stories, and media etc. All technical details pertain to the Hackathon or general AI initiatives, with nothing sensitive.

Let us know if we need to make any changes.

Other changes:

• Adjusted the img styles to make sure they don't stretch when we specify a height attribute which is essential for CLS.
• Tweaked the <figure> short code to meet accessibility guidance (avoiding duplicate alt+caption issue, missing alt issue).
• Added decoding="async" to stop images render blocking the page even with loading="lazy".

Merged: I will open a follow-up linting PR up to look at fixing the other files.
