I was just looking at this, it seems that the package.json is very out of date.

It might take quite a few updates to get this fully working with a new version of electron and we may have to reduce compatibility with older systems, so it would be a major version change, it appears that @cucumber/electron only supports version 12 or 13 of electron as well, so we're unable to go to the latest one.

Version 11 adds support for M1 though:

So version 13 should work.

To support Node 16, we will need to upgrade to Electron 15:

https://www.electronjs.org/blog/electron-15-0

Which would require removing packages that don't support Electron versions after version 13.

In this PR, I have upgraded to version 13:

#347

We will need a PR after this to upgrade to version 15 (I believe it's better to do this separately given the level of changes that we need to do due to the large gap between the current version of Electron that we are using and the version of Electron that we need to go to).

In particular, this is better separately as version 14 and above require the implementation of @electron/remote which causes a whole range of issues with the current codebase.

This should be re-opened as it's still an issue with the library.
