Migrate Local Pathfinding Python Dependencies to package.xml

[SPDonaghy]

Description

• Resolves to Migrate Python Dependencies for ROS Specific Functionalities from Docker Image to package.xml #89

Added local_pathfinding Python dependencies to the package.xml file
I also removed these dependencies from the base-dev.Dockerfile in a separate SailbotWorkspace branch.

I did not remove NumPy from the Dockerfile, but I still added it to package.xml, which might be redundant but it does make it clear that this package specifically depends on NumPy.

The OMPL dependency is still defined in the base-dev.Dockerfile.

Verification

1. I removed the Python dependencies from base-dev.Dockerfile, then built a new image based off of the new Dockerfile.
2. I modified the Dev Container Dockerfile to use this new image and rebuilt the container.
3. I ran the setup task and then the command pip3 list
4. The Python dependencies specifed both in base-dev.Dockerfileand in local_pathfinding/package.xml were all installed successfully
