Add package.json auto version strategy

[tzyl]

This PR adds a package-json auto version strategy to @osdk/cli as an alternative way of inferring a version from the git-describe strategy.

The vite plugin currently manually reads package.json version field to populate the widgets.config.json manifest. We will want to move this over to share the foundry.config.json parsing and auto version utils from @osdk/cli so that they can use the same git-describe strategy. Although we won't use the package-json strategy as the default it still makes sense to support this as a way of inferring versions.
