Add check access of terms in json data

Hi,

On 2.0.x:

In https://git.drupalcode.org/project/shs/-/blob/2.0.x/src/Cache/ShsTermCac..., there is already:

$this->contexts = ['languages:language_interface', 'user.roles'];

In https://git.drupalcode.org/project/shs/-/blob/2.0.x/src/Controller/ShsCo...

    $access_unpublished = $this->currentUser()->hasPermission('administer taxonomy') || $this->currentUser()->hasPermission('view unpublished terms in ' . $bundle);

...

if (!$published && !$access_unpublished) {
        continue;
      }

So I think this issue can be marked as outdated.
