Deprecate VM2

[helloanoop]

We've had great success with vm2 in running scripts inside a sandbox.
The project vm2 however has been currently discontinued and not recommended for production usage.

The recommended alternative is isolated-vm

We want to eventually move to an alternative that is being maintained. I don't want to rush at the moment. There are plenty more things that stack higher in priority.

Here is how an our tasklist to get this done should look like

• a solid test suite that covers a lot of scripting capabilities
• deprecate vm2, move to a isolated-vm, but allow users to fallback to vm2 via toggle if their tests start start failing
• once the new vm is stable, drop vm2

I investigated isolated-vm and I don't think this is a viable replacement in our use case, because it does not support external or internal node modules like fs laverdet/isolated-vm#27.

Thanks @Its-treason !

I am thinking that we can fork vm2 to bruno's org and release a version under the package @usebruno/vm2
This seems to me a good short term solution until we find a better one.

This or using an existing fork like https://github.com/n8n-io/vm2 / https://www.npmjs.com/package/@n8n/vm2

This fork fixed both vulnerabilities with a workaround.

@Its-treason I have rolled back this PR since it was breaking scripting - #1487

@helloanoop is there anything I can do to get this merged in?
