Merge branch '18849-project-snippets-page-isn-t-really-responsive' into 'master'

Update snippets UI

## What does this MR do?

Updates snippets UI _(mainly mobile view)_ to new UI proposed in #18849.

## Are there points in the code the reviewer needs to double check?

Does anyone know the implementation difference between `app/views/snippets/show.html.haml` and `app/views/projects/snippets/show.html.haml`? I have only been updating the latter as it's the only one I can find implemented. I assume the former is rendered somewhere seeing as there is controllers for it too. But this doesn't seem very DRY from my current perspective.

## Why was this MR needed?
