Check node versions in the matrix strategy.

Update the matrix according to the versions needed for your project and the active versions as reported by Node.js Release Working Group.

For example, change:

strategy:
  matrix:
    node-version: [14.x, 16.x, 18.x]

to:

strategy:
  matrix:
    node-version: [16.x, 18.x, 19.x]
