Context

We share assets between our (multilingual) sites by storing them in our theme override directory, as discussed in #2346.

Bug description

When theme.logo is set to a logo in theme.custom_dir instead of docs_dir, social cards fail to generate with the error:

FileNotFoundError: [Errno 2] No such file or directory: '/[...]/docs/assets/img/logo.svg'

The plugin should ideally be looking in the merged assets directory rather than the directory in docs_dir specifically.
