deno: tests run with `--no-check`

[isaacs]

packages/deno/package.json: deno test ... --no-check. Type errors in Deno test files never fail CI. lint:types covers src only.

Either drop --no-check, or add a separate deno check test/ step. Measure the added CI time first; --no-check may have been added for speed.
