fix: restore node-version matrix dimension in 3 TypeScript workflows

samples-typescript-axios-echo-api.yaml
samples-typescript-encode-decode.yaml
samples-typescript-node-encode-decode.yaml

Node version numbers (16, 18, 20, 22, 24) had leaked into all_samples
as bare integer literals. compute-matrix treated them as fake sample
paths, and the build matrix was replaced wholesale, dropping the
node-version dimension and breaking matrix.node-version references.

Fix mirrors the earlier Python workflow fix:
- Remove version literals from all_samples
- Switch setup output to samples (not matrix)
- Add static node-version: dimension alongside sample: in build matrix
- Update if: guard to check needs.setup.outputs.samples != '[]'
