chore(github-integration): allow null delegatedUser

Bump package version to 0.6.0-rc.2 and update GitHubInstallation type to allow delegatedUser to be null. Clarifies in the comment that delegatedUser is null immediately after installation (we only have installation_id) and is populated after the OAuth code exchange in the /oauth callback.
