editor: remove legacy VPX patcher - #572

Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/checkout@v4, actions/setup-dotnet@v4, actions/upload-artifact@v4. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

For projects targeting .NET 8.0 and higher, specifying a RuntimeIdentifier will no longer produce a self contained app by default. To continue building self-contained apps, set the SelfContained property to true or use the --self-contained argument.
