ci(pacquet): drop --filter so pn -r can call the hidden .test script

Adding --filter=pnpm re-enabled pnpm's hidden-script guard and broke the
invocation with ERR_PNPM_HIDDEN_SCRIPT. Recursive mode bypasses that
guard on its own; --if-present silently skips workspace packages that
don't define .test, so the unfiltered form does the right thing.
