Handle non-standard package names for Pulumi providers

[sammyjoyce]

https://github.com/sst/ion/blob/4fdc960ccf1cc35ab76d4050eeb012c6a336c2d5/pkg/project/install.go#L12C1-L14C2

Currently, ion assumes that all Pulumi provider packages follow the naming convention "@pulumi/provider". However, some providers, such as the Upstash provider, use a different package name format ("@upstash/pulumi").

I am happy to create a pull request to handle any of the non-standard package names if helpful, but thought I'd raise the issue prior in case you already have plans to handle it.

It can be worked around by not including the provider in app.providers (thanks to Garret in the sst discord):

/// <reference path="./.sst/platform/config.d.ts" />
import * as upstash from "@upstash/pulumi"

export default $config({
  app(input) {
    return {
      name: "sst",
      removal: input?.stage === "production" ? "retain" : "remove",
      home: "cloudflare",
      providers: {
        cloudflare: true
      }
    };
  },
  async run() {
    const provider = new upstash.Provider("Upstash", {
      apiKey: process.env.UPSTASH_API_KEY!,
      email: process.env.UPSTASH_EMAIL!
    })

    new upstash.RedisDatabase("SSTUpstash", {
      databaseName: "sst",
      region: "us-east-1",
    }, { provider })
  },
});
