Blows up on generic type parameters so disabling until it's working.

* skip on linter install failure

* Convert to package, JSON null funcs to generics (#16973)

NullValue now takes a generic type parameter instead of an interface arg
to determine the type of null sentinel value to create.
IsNullValue infers its generic parameter to determine the type of null
sentinel value to look for.
At present, there is no way to express a 'nillable' generic type
constraint so the funcs simply take a [T any] which should be fine as
they typically take/return pointer-to-types.
The 'to' package has been reduced to two funcs.

definitions when type aliasing support is added in the future.
