Pin pnpm examples to 1.16.1 and restore strict lib checking in Angular

The update script's @latest resolution served stale registry metadata
again, leaving the two pnpm-based examples at 1.15.1 (same failure as
the 1.16.0 bump). Pin them explicitly.

Drop the skipLibCheck the Angular example gained during 1.16.0
(WEB-4498): the 1.16.1 typings pass strict lib checking, and running
without the flag makes this example a regression test for the
published declarations.
