Update windows-ci for action update for Node.js 24 to set up msvc

[jhmgoossens]

The windows-ci.yml for masters and stables of many coin-or projects use the

      - name: Set up msvc
        if: ${{ matrix.arch == 'msvc' }}
        uses: ilammy/msvc-dev-cmd@v1

But this action msvc-dev-cmd still uses Node.js 20. This results in Warnings in the action Runs like:

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 
and may not work as expected: ilammy/msvc-dev-cmd@v1.

I propose that instead of uses: ilammy/msvc-dev-cmd@v1 we use uses: egor-tensin/vs-shell@v2. This vs-shell action is light-weight and does not use Node.js. Test runs show that such runs work and produce the same binaries. The maintainer is active, even if this action itself has not had recent releases.
