Fix #1624. Search for the image in the page resources.

[valnaumov]

Fixes image URL for multilingual sites when the image resource is only defined for the default language.

What does this PR change? What problem does it solve?

PaperMod defines a custom figure shortcode which currently fails to provide a valid link in a multilingual site. As stated in Hugo docs, we should be able to use image resources from any page bundle.

The old shortcode uses the img src as is without searching for the resource in other page bundles. See the linked issue for an example.

Was the change discussed in an issue or in the Discussions before?

Closes #1624
