Shouldn't flag `as unknown`

[danielnixon]

Version(if relevant): 2.8.1

Environment(if relevant):

Code(if relevant):

const foo = someAnyValue as unknown;

Expected:

as unknown should be allowed (even in strict mode). Consider an any (or some other bad type) from a third party library that you want to treat (safely) as unknown.

Actual:

as unknown is flagged as untyped (when in strict mode).
