enhancement: update screenshots

[jamesericdavidson]

README screenshots are out of date:

• Copyright year (now.Year) is 2023
• [x] Update Home page screenshot
• [x] Update Posts page screenshot Home page and Posts page need yearly updates.
• [x] Update Documentation - Basics screenshot (#243, #233)
• Replace Performance (Google Lighthouse) screenshot with higher resolution Wait for #250 (#260, #261)

Low priority and good first issue.

This has been pending for a long time, thanks @jamesericdavidson

We already have a screenshots.py script for this purpose. I had tried running it a few weeks back but there were some errors.
Ideally, whoever picks this up should update the screenshot.py script and use that to generate the updated screenshots. cc @yashmehrotra

@526avijitgupta I think we should combine this with #184, and approach this in a cloud-native fashion: see #262.

Narrowing the scope of this issue down - #263 will close this.

Will be tracking #262 and #184 separately, keeping the Containerfile and screenshot.py fixes together for portability.
