New: Previous Provider Version Docs in Pulumi Registry

Pulumi has enhanced its Registry by allowing users to browse documentation for previous versions of first-party Pulumi providers, eliminating the need to search through Git history or guess changes. This feature supports Pulumi Neo and other agents in providing more accurate assistance with Pulumi code and operations. Users can now select from a version dropdown on a provider's page to view the full API documentation for the current version and the latest release of the two previous major versions. For instance, if a provider is on version 7.x, documentation for versions 6.x and 5.x is also accessible. Users are encouraged to explore this feature and provide feedback through Pulumi Community Slack or GitHub.
