B. Scott Michel 0f9ecd1d55 CI/CD: Update Github runners
- macos-13: Deprecated and gone.

- checkout, upload-artifact: Github action script version changes.

- windows-latest (aka windows-2025): Leave future TODO notes in
  cmake-builds.yml. It's pointless to build on windows-2025 since there
  is no newer Visual Studio version than VS 2022 and doing so will
  produce the exact same package outputs.

Open SIMH machine simulator

This is the codebase of SIMH, a framework and collection of computer system simulators.

SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.

The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.

PLEASE NOTE

Do not contribute material taken from github.com/simh/simh unless you are the author of the material in question.
