ci: allow Node 10/12 test rows to fail without blocking the workflow

Some bundled CSS minimizers (`@swc/css` requires Node 14+, `esbuild`
0.27 requires Node 18+) cannot load on Node 10/12. The matrix still
exercises those Node versions for visibility, and `fail-fast` is now
disabled so newer rows aren't cancelled when an older row fails.
