Remove `AddViteApp` and `WithNpmPackageInstaller`

[aaronpowell]

Some of the Node.js extensions package is going to be part of Aspire 13, dotnet/aspire#12283 is the PR that the changes landed, so we need to remove those from the CT.

The Yarn and pnpm support aren't moving across, but the annotation types have been moved, so we should use the annotations from Aspire and set them up with yarn/pnpm.

I think we can move these 2 across as well. We have some follow up work in dotnet/aspire for making the NodeJS integration better.

Will they move for the Aspire 13 release? If so, we can track them as part of this work, otherwise we'll spin a seperate issue.
