feat: add Pinecone serverless index templates

[dirien]

Hi,

This PR adds starter templates for the Pinecone provider only for serverless indexes

[scottslowe]

This looks good (only one minor change needed on the Python program), but we'll need to include a C# template here as well (or follow up very quickly with a C# template).

Hi @scottslowe,

thanks for the feedback and review! I must forgot the C# example, but now it is added!

Looking forward for you review.

@dirien Can we build a Java template also?

@cnunciato we did not generated a Java SDK for the moment!

How does one use these templates? When I run the TypeScript template with an API key for example, I get this:

Diagnostics:
  pulumi:pulumi:Stack (pinecone-serverless-typescript-03f0d18-dev):
    error: update failed

  pinecone:index:PineconeIndex (my-example-index):
    error: Failed to get Pinecone index: example-index-ts with http error code: 404
    error: failed to get Pinecone index: example-index-ts

Does the template not create the index? Should we prompt for some of these values, then (e.g., index name, AWS region)? Should we revisit the resource, variable, and output naming across all of these templates to be more consistent? And if it's a starter template, shouldn't we instead name it pinecone-$language? (cc @scottslowe)

Chatted with @dirien and the error may be because my account doesn't have early-access perms for this feature. #729 renames the templates pinecone-$language. We'll add the prompting with defaults in a follow-up.
