I had a few questions, but otherwise OK.

Tried out this PR, have a couple of notes:

• When opening the container for the first time, I got the error message that the workspace folder does not exist.
• I got the message "Visual Studio Code is unable to watch for file changes in this large workspace" (error ENOSPC). See link for resolving this
• We may want to exclude some of the subdirectories in .cache from being watched for file changes since it contains the conda repo and a bunch of other files that arent source code. You can do that with the setting "files.watcherExclude"
• The extensions should be updated. A good set would be to use the following:

        "cschlosser.doxdocgen", // Adding docstrings to C++ code
        "eamodio.gitlens", // Enhanced Git support
        "eeyore.yapf", // Python code formatter
        "josetr.cmake-language-support-vscode", // CMake language support
        "llvm-vs-code-extensions.vscode-clangd", // Clangd language server for C++
        "matepek.vscode-catch2-test-adapter", 
        "mechatroner.rainbow-csv", // Colorizing CSV files
        "mhutchie.git-graph", // Visualizing Git history and branching
        "ms-azuretools.vscode-docker", // Docker support
        "ms-python.debugpy", // Python debugger
        "ms-python.flake8", // Python linter
        "ms-python.isort", // Python import sorter
        "ms-python.pylint", // Python linter
        "ms-python.python", // Python language support
        "ms-python.vscode-pylance", // Python language server
        "ms-toolsai.jupyter", // Jupyter notebook support
        "ms-vscode.cmake-tools", // CMake support for building Morpheus
        "ms-vscode.cpptools", // C++ language support
        "njpwerner.autodocstring", // Adding docstrings to python code
        "nvidia.nsight-vscode-edition", // CUDA integration and debugging
        "stkb.rewrap", // Wrapping all text in any language
        "vadimcn.vscode-lldb" // LLDB debugger (better than GDB for C++ debugging)

• The conda environment should be automatically installed or updated.

Remove the .devcontainer/devcontainer.json which was duplicated from a merge and we are good to go.
