Remove link from node title in Card display mode to improve accessibility

This doesn't need to do so much. We addressed the WCAG link purpose for the "view bundle" in the previous issue.

Now that #2937639: Umami Theme - a11y context is needed for read more links is fixed, the remaining thing is to remove the links from the node title in these card templates.

This was supposed to be a simple follow-up for something that was already agreed by the OOTB maintainers, in #2937639-10: Umami Theme - a11y context is needed for read more links.

The problem with this tabindex approach is it creates inequality, by treating users differently. Putting users into separate silos isn't good for accessibility or inclusion.

• Sighted pointer users can click on the link title.
• Sighted keyboard users, without assistive technology, can't operate the title link They may not be aware of it at all..
• Screen reader users will not encounter this link if tabbing through the page, but it will be reported in the "list of links" tool, and they may encounter it in normal reading mode, or using the "next link" command

.

Now imagine three such users are having a conference call, and the mouse user says "click the title"....

(I think we should also link the image itself to the article/recipe, and skip it the same way as the above solution, but perhaps that should become a separate issue?)

This was already removed in a previous issue.
