Do not indicate to wombat that we are running inside a SW since we are not

[benoit74]

This is a draft PR because while it allow to solve the problem in #293, it breaks youtube videos (and probably other things)

I don't really get yet why we used to indicate to wombat that we are running inside a Service Worker since we are not.

Git history is not very clear, and this was one of the undocumented option indicated to be solved in https://github.com/openzim/warc2zim/issues/239 ; @mgautierfr do you have any explanation to share?

I tested this with all test cases from the test website and they seems to all responded positively except the Youtube video.

Not really. Some mix of copy/paste and "it was working". BTW, I don't know what is the real impact on wombat when we set (or not) this config option.

Speculation: The Replay Worker could be run either as a Service Worker or as a Web Worker. Is it possible that some URLs would be rewritten differently if they were intended to be caught by a Service Worker as opposed to being "sent" to a regular Worker?
