Old description:

> Instead of manually building html tag in 2016 for custom header, use the
> `the_header_image_tag` function.

New description:

 There are a number of core themes that do not use the
 `the_header_image_tag` function. This function was added in WP 4.4 after
 some of these theme were introduced. Add a backwards compatibility shim to
 use this function in core themes.

 See the following core themes that need to be updated.
