Fix issue in a custom token used in two places in the metatag config

Reported by Mohammed J. Razem

in a custom token
open view-source: in the browser

see

"logo": {
                    "@type": "ImageObject",
                    "url": "http://localhost/sandboxes/varbase7test5/docroot//logo.png"
                }

It’s a wrong token that we need to update

[current-theme:path] should be [default-active-theme:path]
it’s used in two places in the metatag config
