Make nuxeo-data-grid usable with keyboard only.

Location:

• "Search results" section

Except for the first item in the search results section, all the other links do not receive the keyboard focus and are not accessible using the keyboard alone.

Recommendation to fix
RULE :
Functionality MUST be available using the keyboard, unless the functionality cannot be accomplished in any known way using a keyboard.

HOW TO FIX:
Fix this issue by ensuring the component can be used by the keyboard OR by providing a conformant alternate functionality method for the action

BACKGROUND:
Some people cannot use a mouse due to vision or motor disabilities. Content that can be operated with a mouse must also be made operable with a keyboard. When content is operable through a keyboard, it becomes operable by a variety of assistive technologies such as speech input software, sip-and-puff software, on-screen keyboards, scanning software, and alternate keyboards.
