chore: remove Node 20 from CI matrix

[Copilot]

Node 20 reached EOL on April 30, 2026. This PR removes it from the CI matrix.

Changes

• Remove lts/-2 (Node 20) from the build matrix — now only lts/-1 (Node 22) and lts/* (Node 24) are tested
• Update the deploy-docs job to use node-version-file: '.nvmrc' instead of a hardcoded version
