Pass electron version to checkers

[JarLob]

Some differences between electron versions were already found like https://github.com/electron/electron/blob/master/docs/api/breaking-changes.md#browserwindow
and it is likely more will be found in the future.

Just a quick summary of the current state and this issue:

• Electron is quickly evolving, and many APIs are changing between major versions
• Checks require precise naming for detecting misconfigurations. The current implementation is simply looking for multiple setting names
• Ideally, we could detect the specific version in use and limit checks to the valid API names / syntax
• As we may not be able to understand the specific version used (e.g. scan of a single file), we would need to check for all syntaxes anyway

Is this going to increase the overall complexity for just a minor performance gain? What do you think? Any additional benefit?

[JarLob]

It should increase complexity only slightly in some checkers as the number of differences in electron versions is still low. Plus an additional scan step is needed to read version first. However it is not about performance gain but about precision of analysis. For example it is planned in the future to change the default values of webpreferences. Settings parsing was fixed
electron/electron#15594 although not sure in what version, so technically two settings parsing functions are needed for older and newer electrons.
