Lazy load commons images and stop fetching them in SSR mode

## Background Information
From the new relic dashboard we identified that the personality pages have slow outliers and one thing we can do to improve is stop rendering commons images during SSR. Fetching the image takes up to 25% of the loading time, see image below.

## How
[Look at the Next.js documentation for lazyloading component](https://nextjs.org/docs/app/building-your-application/optimizing/lazy-loading). The component that needs to be lazyloaded is [AletheiaAvatar.tsx](https://github.com/AletheiaFact/aletheia/blob/stage/src/components/AletheiaAvatar.tsx)
