Manage Node.js version using .node-version file

Goal

Ensure the Node.js version is consistent across different environments by using a .node-version file.

How

1. Find the current Node.js version from actions/setup-node in the GitHub Actions workflows.
2. Create a .node-version file in the root of your repository.
3. Change the actions/setup-node step in your GitHub Actions workflows to read the .node-version file.

Example

Before:

- uses: actions/setup-node@v4
  with:
    node-version: 20.19.5

After:

- uses: actions/setup-node@v4
  with:
    node-version-file: .node-version

Acceptance Criteria

• A .node-version file is created in the root of the repository with the correct Node.js version.
• All actions/setup-node steps in GitHub Actions workflows are using node-version-file input.
• All actions/setup-node steps in GitHub Actions workflows are not using node-version input.
