Redundant alt attribute. Screen-readers already announce `img` tags as an image code example

Example: jsx-a11y/alt-text

<img src="foo" alt="Foo eating a sandwich." />
<img src="foo" alt={"Foo eating a sandwich."} />
<img src="foo" alt={altText} />
<img src="foo" alt={`${person} smiling`} />
<img src="foo" alt="" />

<object aria-label="foo" />
<object aria-labelledby="id1" />
<object>Meaningful description</object>
<object title="An object" />

<area aria-label="foo" />
<area aria-labelledby="id1" />
<area alt="This is descriptive!" />

<input type="image" alt="This is descriptive!" />
<input type="image" aria-label="foo" />
<input type="image" aria-labelledby="id1" />
