Given an HTML string, replace any static file paths like
/static/foo.png
(which are really pointing to block-specific assets stored in blockstore)
with working absolute URLs like
https://s3.example.com/blockstore/bundle17/this-block/assets/324.png
See common/djangoapps/static_replace/__init__.py
This is generally done automatically for the HTML rendered by XBlocks,
but if an XBlock wants to have correct URLs in data returned by its
handlers, the XBlock must call this API directly.
Note that the paths are only replaced if they are in "quotes" such as if
they are an HTML attribute or JSON data value. Thus, to transform only a
single path string on its own, you must pass html_str=f'"{path}"'
