Add a default for saveBeforeStart setting

[TylerLeonhardt]

All you have to do is add:

"configurationDefaults": {
      "[powershell]": {
        "debug.saveBeforeStart": "nonUntitledEditorsInActiveGroup"
      }
    },

under contributes in the package.json.

here's an example:
https://github.com/microsoft/vscode/blob/bce4d71f648a963cad905ee0ecc7b353ddd3f199/extensions/markdown-language-features/package.json#L311

Then Untitled file debugging will no longer prompt to save :)

Note: VS Code made this setting "language-aware" literally today. So this will work starting with tomorrow's insider build. There's no downside of this being set for those folks on older versions of VS Code so this change can really go in whenever.

Is this a duplicate of #3200?

[SydneyhSmith]

Yep, looks like this would resolve #3200

[TylerLeonhardt]

This is a better solution than the other :)

@TylerLeonhardt Is this new enough?

It doesn't seem to be working...maybe I have something else going on.

[andyleejordan]

I've double checked what I added to package.json against microsoft/vscode#117100 ...hm, I'll open a draft PR and maybe I erred?

[TylerLeonhardt]

Yeah it looks like that setting isn't working as expected. @isidorn, any thoughts?

[isidorn]

Thanks for doing this PR.
There was an issue on the VS Code side that I tackled via microsoft/vscode@779f987

So now it should work. I tried it out.
You can verify with vscode insiders from Monday. Thanks a lot 👏
