Pin Node.js 24 in release workflow

[codebycarson]

This pull request makes a minor update to the Node.js setup step in the release workflow. The change specifies Node.js version 24 directly instead of using the .nvmrc file, and clarifies the step's purpose for npm OIDC publishing.Replace node-version-file: '.nvmrc' with an explicit node-version: '24' in the release GitHub Actions workflow and rename the step to 'Setup Node.js (for npm OIDC publishing)'. This ensures the workflow uses Node 24 for npm OIDC publishing rather than relying on the repo's .nvmrc.

Release workflow now pins Node.js 24 while the rest of CI (e.g. checks.yml/coverage.yml) still uses .nvmrc (currently v20). This means the build+publish path can run on an untested Node major, which can lead to release-only failures or different build output. Consider aligning versions (update .nvmrc to 24, or switch other workflows to 24 / add a Node matrix including 24) so release runs on a version covered by CI.
