NodeJS esnext results coud use update for featuer released in v14 semver-minors

NodeJS now supports private (static) class methods and fields by default (since node-v14.10 i think). so it passes all current stage-3 tests without any flags.

here's the result of running the es-next test in node-v14.13:
```log
▼ instance class fields
✔ public instance class fields
✔ private instance class fields basic support
✔ private instance class fields initializers
✔ optional private instance class fields access
✔ optional deep private instance class fields access
✔ computed instance class fields
▼ static class fields
✔ public static class fields
✔ private static class fields
✔ computed static class fields
▼ private class methods
✔ private instance methods
✔ private static methods
✔ private accessor properties
✔ private static accessor properties
▼ Legacy RegExp features in JavaScript
✔ RegExp "lastMatch"
✔ RegExp.$1-$9
✔ Hashbang Grammar
```

Similarly Weak References are enabled by default now aswell (also v14.13, tested --but forgot-- if they ran in 14.10 aswell):

```log
▼ WeakReferences
✔ WeakRef minimal support
✔ FinalizationRegistry minimal support
```
