Enable running on Node 16 versus current Node 12

[Toffetor]

Seems Node 12 runner operation is about to go depreciated, any plans to update repo to Node 16 status? Ref warning:

Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: actions/setup-java, NuGet/setup-nuget, MirageNet/nunit-reporter, actions/setup-java
