Do not generate default alt text in image tags
- Auto-generating content from the filename of an image is not suitable
alternative text; alt text that isn't fully considered can be
distracting and fatiguing for screen readers users (blind, low vision,
dyslexic people).
- Setting a filename fallback short circuits screen reader default
behavior and configuration for blank descriptions.
- Setting poor defaults also creates false negatives for accessibility
linting and testing software, that makes it harder to improve
application accessibility.
***
- After this change, if authors leave images without alt text, screen
readers will fallback to default behavior for missing alt text.
- Also with this change, Automated linting and testing tools will
correctly generate warnings.
[Fixes #30096]
