upgrade CI to Node 24 to fix broken npm in Node 22.22.2 tool cache

The ubuntu-24.04 runner image (20260329.72.1) ships with a corrupted
Node 22.22.2 tool cache: npm 10.9.7 is missing `promise-retry` from its
own module tree, causing any `npm install -g` to fail with
MODULE_NOT_FOUND. This broke all nodejs SDK build jobs.

Node 24 ships with npm 11 natively, which supports OIDC Trusted
Publishers without requiring a separate upgrade step, so we can drop the
`npm install -g` workaround entirely.
