Aria-Label required on reviews for compliance

To whom it may concern,

I am currently working on a clients website and accessibility is very important to them. Whilst using this accessibility scanner (https://accessibe.com) I came across a few things that need to be implemented within your plugin.

Links that open in new tabs/windows should be tagged for assistive technology
Links that open in a new tab or a new window should either have an “aria-label” attribute or a screen-reader only element explaining to screen-readers that this opens in a new tab.

This is the link inside of the Rating Layout widget
<a target="_blank" rel="nofollow noopener" ><span>Hygiene Daheim GmbH</span></a>

These are the links inside of the Slider Layout widget
<a class="wp-google-name" target="_blank" rel="nofollow noopener" >Magdalena</a>

Interactive elements should be navigable using the keyboard
Interactive elements such as links, buttons and form fields should all be navigable using the keyboard by either using a focusable element (a, button, input, etc.) or including the “tabindex” attribute that equals to “0”.

These are the next and previous buttons of the Slider Layout widget
<div class="grw-btns grw-prev" ><svg viewBox="0 0 24 24"><path d="M14.6,18.4L8.3,12l6.4-6.4l0.7,0.7L9.7,12l5.6,5.6L14.6,18.4z"></path></svg></div>
<div class="grw-btns grw-next" ><svg viewBox="0 0 24 24"><path d="M9.4,18.4l-0.7-0.7l5.6-5.6L8.6,6.4l0.7-0.7l6.4,6.4L9.4,18.4z"></path></svg></div>

I hope you can assist with an update to your plugin to help make it more accessible compliant.
