Add support for GitURL and Dockerfile in Execution Container Images

[mcasperson]

This PR exposes the git_url and dockerfile properties on the container images.

[Copilot]

Pull request overview

This PR adds Terraform surface area for Octopus “execution container image” fields by exposing git_url and dockerfile alongside existing feed_id/image, across both the legacy SDKv2 schemas and the newer Plugin Framework resources.

Changes:

• Extend the SDKv2 DeploymentActionContainer expand/flatten + schema to include git_url and dockerfile, with a unit test update.
• Extend Framework process step container schema/model and mapping logic to round-trip git_url/dockerfile (including updated mapping tests).
• Bump github.com/OctopusDeploy/go-octopusdeploy/v2 dependency and update generated docs to include the new attributes.
