fix(compiler-cli): use @ts-ignore. (#47636)

The previous commit 2e1ddde used `@ts-expect-error` to suppress the
current error, with the intent of being informed once that's no longer
an error, ie. when we updated to an upstream TS version that includes
this change.

However this unfortunately means the change is incompatible with the
fixed version, which prevents it from working with an updated TS version
in google3.

This change reverts back to the original `@ts-ignore` which is forwards
and backwards compatible, avoiding that problem (but unfortunately
losing the benefit of being notified once fixed).
