[4.0] mod_syndicate a11y and more

[brianteeman]

Problem

1. the alt text contains the word image which is not recommended
2. the alt text is hardcoded and not translatable
3. When the text is displayed then the alt text is not needed as it does not convey any meaning
4. When the text is not displayed then the use of the image as a link with an alt of feed-image does not convey the meaning of the link

Solution

1. remove the alt text completely and replace with empty alt
2. when the text is not displayed give it a sr-only class so that the link has meaning instead of just removing it completely
3. as a result change some language strings and re-order the fields so that they make more sense and remove the show-on

Testing

If you dont already have a syndication module then create one

The changes are visible in the config of the module

Before

After

In the frontend the changes are only visible in the markup of the module

After - with Label

After - without label
