Translate screenshots for the About page

[oglekler]

Many locales' polyglots are working on translating the About page and providing great experience and clear information for local native language users, but screenshots cannot be replaced and translated, and as a result, what is highlighted in the screenshots looks different in the translated admin interface.

I propose to translate images src for screenshots with text as well and provide logic for that.

The path to images can be restricted to WordPress CDN and the images themselves can be uploaded by GTE to a local media library, or the images can be submitted separately somewhere before actual strings translation.

@oglekler thanks for your efforts on this. Is this to be milestoned for 6.4? If so, would it be useful to have a dev note?
