Time to update acorn-node?

Latest https://github.com/browserify/acorn-node/ is 2.0.1, insert-module-globals uses effectively 1.8.2, which is from 2020, and doesn't support some JS syntax, which would be useful.

Actually this would affect a few other packages too:

```
│ └─┬ browserify@17.0.0
│ ├─┬ insert-module-globals@7.2.1
│ │ ├─┬ acorn-node@1.8.2
│ │ │ └── acorn@7.4.1
│ │ └─┬ undeclared-identifiers@1.1.3
│ │ └─┬ acorn-node@1.8.2
│ │ └── acorn@7.4.1
│ ├─┬ module-deps@6.2.3
│ │ └─┬ detective@5.2.1
│ │ └─┬ acorn-node@1.8.2
│ │ └── acorn@7.4.1
│ └─┬ syntax-error@1.4.0
│ └─┬ acorn-node@1.8.2
│ └── acorn@7.4.1
```
