Impact of EcmaScript Module (ESM) Loading of VS Code

[isidorn]

We are in the process of changing how our code is loaded in VS Code core, away from AMD/CommonJS to ESM. Extensions will continue to load as CommonJS, but this change comes with change to the require method: Specifically, require.main will be undefined beginning with our 1.94 release.

If you have a usecase for accessing a file from the installation, please consider vscode.env.appRoot instead or reach out to us.
