audrasjb bc39cfc822 Bundled Themes: Cast font URL functions to string for add_editor_style().
This changeset ensures the result of the font URL functions is a `string` before using it in `add_editor_style()`, to avoid PHP warnings on child themes. This similarily updates Twenty Thirteen, Twenty Fourteen, Twenty Fifteen, Twenty Sixteen, and Twenty Seventeen.

Props jordesign, SergeyBiryukov, sabernhardt, huzaifaalmesbah, shailu25.
Fixes #59704.
