exposing network project id

[kadupoornima]

This pull request enhances the network modules by exposing the project ID associated with VPC networks and subnetworks. By adding these as output variables, users gain better visibility into the infrastructure state. Additionally, the custom image module was updated to allow for more flexible project ID configuration during image building, ensuring better compatibility with cross-project network deployments.

Changes:

• Network Project ID Exposure: Added 'network_project_id' and 'subnetwork_project_id' outputs across multiple network modules to improve visibility into the project context of provisioned resources.
• Packer Custom Image Enhancement: Updated the custom image module to support 'subnetwork_project_id' and improved the logic for setting 'network_project_id' in the Packer configuration.
• Documentation Updates: Regenerated documentation for all modified modules to reflect the new output variables and input parameters.

Code Review

This pull request updates several network modules—including gpu-rdma-vpc, multivpc, pre-existing-subnetwork, pre-existing-vpc, and vpc—to provide project ID outputs for both networks and subnetworks. The packer/custom-image module is also updated to include a subnetwork_project_id input, which serves as a fallback for network_project_id. Furthermore, the README documentation for these modules has been refreshed with standardized table formatting and updated input/output definitions. I have no feedback to provide as there were no review comments to assess.
