Normalize spelling of "ServiceWorker Mode" vs "Service Worker"

[Jaifroid]

We are currently inconsistent in sometimes using "Service Worker Mode" and (mostly) "ServiceWorker Mode". In the files touched by #903 I have normalized this to "ServiceWorker Mode" (since it is what we mostly use), but when discussing "Service Workers" (not followed by "Mode", I retain the space. However, there are many other places in the app where this is inconsistent, and it would be good to normalize elsewhere. It's out of scope for #903 because it would introduce a lot of noise into the PR.

@Jaifroid Let me know if I can complete this existing issue

[Jaifroid]

@Daksh119 I think this is no longer an issue since the internationalization of the app recently. Sorry it wasn't closed earlier. I'd recommend finding another issue to work on.
