allow more characters in "sameAs" field? or convert to multivalue single fields?

I've added a Merge Request that pretty bluntly increases the size of all URL metatag fields to 1024. This is probably not the best way to do this, but it solves the ask quickly. Patch is at https://git.drupalcode.org/project/schema_metatag/-/merge_requests/90.diff

Going to set to "Needs work" so other folks can do something more elegant, like the multi-field suggestion.
