fix(patchUrlMappings): attemptSetNodeSrc on node itself, not only children

Super-opinionated-pedantic nit

We should rename the function to recursivelyRemapNodeAndChildNodes

or we can call attemptSetNodeSrc inside the original mutation's added nodes

  if (patchSrcAttributes) {
    const callback: MutationCallback = function (mutationsList) {
      for (const mutation of mutationsList) {
        if (mutation.type === 'attributes' && mutation.attributeName === 'src') {
          attemptSetNodeSrc(mutation.target, mappings);
        } else if (mutation.type === 'childList') {
          mutation.addedNodes.forEach((node) => {
            attemptSetNodeSrc(node, mappings);  // Heres the added line
            recursivelyRemapChildNodes(node, mappings);
          });
        }
      }
    };

Either works. I'm pro the code-snippet above as it should result in less function calls. But we should double-check that it still solves the core issue
