'general.useragent.override' pref and then set
'general.useragent.override' to 'Macintosh; Intel Mac OS X 10.13'
Thanks for the guidance. Kathy and I hacked `Navigator::GetUserAgent()` to
respect `general.useragent.override` and set that pref to `Mozilla/5.0
(Macintosh; Intel Mac OS X 10.13; rv:60.0) Gecko/20100101 Firefox/60.0`.
The result is that our tests with both GitHub and Google Docs were
successful: the command key is correctly recognized on macOS.
I am not sure what the next step is; it looks like it will not be trivial
to create a shippable patch (since `Navigator::GetUserAgent()` expects to
get the userAgent string from the HTTP protocol handle, but we want HTTP
to use a spoofed `User-Agent`).
