[BUG]: building `runtime` target fails at `git_clone` when Morpheus is a submodule

Version

24.10

Which installation method(s) does this occur on?

Docker

Describe the bug.

When trying to build the Morpheus Docker container using the runtime target, the build fails at the git_clone stage.

The relevant line in the error log is the following:

#0 0.570 fatal: not a git repository: /opt/host_repo/../../.git/modules/morpheus

I believe the issue is in Dockerfile lines 298-300. This command does a local clone from an existing cloned morpheus repo located at MORPHEUS_ROOT_HOST using the info in its .git/ directory. However, when morpheus is a submodule, the .git file points to the relative path ../../.git/modules/morpheus, which doesn't get mounted to the container and therefore doesn't exist.

Minimum reproducible example

From within the submodule root:

MORPHEUS_ROOT_HOST=. ./docker/build_container_release.sh
