External link under child menu not translatable

I am also seeing this issue on one of my projects. Patch attached is to recursively iterate through child menu links to process them the same way as parent menu items are processed.

#6 Worked like a charm on our production running project
Additionally, I reviewed the code that is looking good to me

I just ran the patch and everything looks good. Once it was recursvively bouncing through child menu items it started working as expected.

Hi Anish, Your code is merge in 8.x-1.x-dev Branch. Please review once at your end as well.
