build(devtools): target es2020 explicitly

We do this because of a bug caused by evanw/esbuild#2950 and a recent change to how angular static properties are attached to class constructors. Targeting esnext or es2022 will currently cause component and factory fields on class constructors to reference a class constructor variable that they do not have access to.

Because of this we explicitly target es2020 in our Angular DevTools builds.
