Not compatible with babel/core v8+

After updating `@babel/core` to v8.0.1 I'm getting the following error:

```
npm error code ERESOLVE
npm error ERESOLVE could not resolve
npm error
npm error While resolving: grunt-babel@8.0.0
npm error Found: @babel/core@8.0.1

npm error
npm error Fix the upstream dependency conflict, or retry this command with --force or --legacy-peer-deps to accept an incorrect (and potentially broken) dependency resolution.
```

It seems that this project requires v7 only.

Is this ever likely to get fixed, or has this project now been abandoned?

Start by reproducing the npm install failure with @babel/core 8.0.1 and inspect how grunt-babel declares and uses its @babel/core dependency. Done means the package installs with Babel 8 without the reported peer-dependency conflict and its existing compatibility checks still pass.
