fix(pulumi): explicit repo path in plugin install URL

Pulumi's 'github://api.github.com/{owner}' URL form derives the repo as
'{owner}/pulumi-{plugin-name}', i.e. it expects 'numberly/pulumi-mica'.
Our actual repo is 'numberly/terraform-provider-mica' so the implicit form
404s. Use the two-segment form 'github://api.github.com/{owner}/{repo}' to
point at the right release source.

Apply the fix to both the goreleaser-rendered release notes and the
pulumi/README.md install snippet.
