refactor: add vscode dev container config file

[rickstaa]

What does this pull request do? Explain your changes. (required)

This is my first attempt at creating a working Vscode dev container for the go-livepeer repository. This development container will greatly simplify me dev workflow in cases where the AI subnet fails inside a container but not when using the binary.

Specific updates (required)

How did you test each of these updates (required)

Does this pull request close any open issues?

[rickstaa]

@eliteprox, @ad-astra-video, I've been setting up a development container this morning to simplify debugging the timeout issues with external containers as reported in LIV-299. I managed to get the build running, but I'm encountering errors when attempting to use the go-livepeer binaries within the development container. These seem to be related to missing permissions, mounts, environment variables, or configuration values. Have you come across these errors before?

Steps to Reproduce Errors

Debugging Setup

1. Open the repository in VSCode.
2. Click on Reopen in Container to initiate the container setup.
3. Ensure the development container builds successfully.
4. Insert the following configuration into your .vscode/launch.json:

{
    "name": "Launch Transcoder",
    "type": "go",
    "request": "launch",
    "mode": "auto",
    "program": "${workspaceFolder}/cmd/livepeer",
    "buildFlags": "-tags=mainnet,experimental",
    "env": {
        "GO111MODULE": "on",
        "CGO_ENABLED": "1",
        "CGO_LDFLAGS": "-L/usr/local/cuda/lib64 -L/home/elite/compiled/lib",
        "PATH": "/usr/local/cuda/bin:${PATH}",
        "PKG_CONFIG_PATH": "/home/elite/compiled/lib/pkgconfig",
        "LD_LIBRARY_PATH": "/home/elite/compiled/lib"
    },
    "args": [
        "-transcoder",
        "-nvidia", "0",
        "-orchAddr", "https://127.0.0.1:8935",
        "-orchSecret", "1234",
        "-cliAddr", "127.0.0.1:7926",
        "-maxSessions", "5",
        "-dataDir", "/livepeer/arbitrum-one-mainnet/transcoder",
        "-v", "7"
    ]
}

5. Start the debugging session and monitor for errors.

Build Errors

1. Open the repository in VSCode.
2. Click on Reopen in Container to initiate the container setup.
3. Confirm the development container builds successfully.
4. Follow the go-livepeer documentation to build the Livepeer binaries.
5. Observe the build errors listed below:
