chore(tests): remove old screenshots without a test (#29472)

Issue number: internal

---------

## What is the current behavior?
Several screenshot images were not removed when their e2e test was.

## What is the new behavior?
I ran the following command in `ionic-framework/core` to find all
`*.png` files that did not have a parent `*.e2e.ts` file:

```bash
find ./src/components -iname '*.png' -exec bash -c 'cd "${1%/*}"; 
  shopt -s nullglob; files=(../*.e2e.ts); 
  ((${#files[@]} == 0)) && echo "$1"' _ {} \;
```

I have deleted all of these images.
