I’m moving my standalone code over to a worker using the automation api, based on the examples i gather i have to install plugins by calling `await stack.workspace.installPlugin("aws", "v3.6.1");`and that they are not installed automatically like in the stand alone version? And, where can i find the possible versions?

If you look at the releases page on any of our provider repos, you can see the full list of available versions: https://github.com/pulumi/pulumi-aws/releases
