getTag function should allow to return strings

Hi @Dave Reid,
I have solved this issue and also created MR for this i.e. "getTag function should allow to return strings". Kindly review the changes.

Thank you.

I applied the proposed patch and got the following:

 TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given in count() (line 98 of /home/mmex/public_html/web/modules/contrib/metatag/src/Entity/Me  
  tatagDefaults.php).    

I changed line 98 to check if $tag is of type array:

if (is_array($tag) && count($tag) === 1) {
            return reset($tag);
        } 

I don't know how to create a MR.

@apparatchik I applied you fix to the patch.
