Apply image style to default picture

Description of the need

If you ever set the Default picture on admin/config/people/settings, then you could have an impression the settings in the next section for Picture display style would apply to the default picture.

Unfortunately, it's not true as the HTML-code always shows:

<img src="http://in.docksal.site/files/pictures/default_image.png" alt="Backdrop CMS's picture" title="Backdrop CMS's picture">

for the default picture. However, if a user uploads his/her own picture, then the image style kicks in:

<img src="http://in.docksal.site/files/styles/thumbnail/public/pictures/picture-1-1614678151.png" alt="Backdrop CMS's picture" title="Backdrop CMS's picture">

Proposed solution

I don't see any reasons for the style selected in Picture display style section not to be applied for also the default picture. If you, guys, support this feature request, then I could offer a respective PR.
