Electron version not read from package.json if WDIO config is in a subdir

[christian-bromann]

If the wdio.conf.js file is in a sub directory, the service won't find the Electron version automatically anymore because the config file is not located next to a package.json anymore. I suggest to use pkg-up to find the closest one.

Presumably we also want to use pkg-up in the docs and examples when finding the productName for passing to getBinaryPath.

Is there any way we can assume a good default here and allow users to set only if desired. It would be amazing if users don't have to set anything if they follow the default setup.

I will look into this.

Let's just keep this issue about getting the electron version from package.json, the productName case is a different thing.
