fix: Dynamic port for LEARNING MFE in form of ENV variable

[ktyagiapphelix2u]

Description

This PR adds dynamic port for LEARNING MFE in form of ENV variable

• It will update all MFE related files dynamically
• It will update python configuraiton files by referencing ENV variable

It is done in this manner so that by just changing the value here, it will update all required frontend-repositories.
And take the value dynamically.

Pull Request Overview

This PR introduces dynamic port configuration for the LEARNING MFE (Micro Frontend) by replacing hardcoded port 2000 with environment variables that default to port 2010.

• Updates environment variable references across Python configuration files and Docker Compose
• Adds script to dynamically update .env.development files for all frontend applications
• Modifies devcontainer configuration to use the new port and environment variables

The variable LEARNING_MICROFRONTEND_NETLOC is used but not defined in this file. This will cause a NameError when the code runs.

The os module is used but not imported. Add 'import os' at the top of the file to avoid a NameError.

The default port value 2000 is inconsistent with the new default port 2010 used elsewhere in the codebase. This should be 2010 for consistency.

Suggested change

	PORT=${LEARNING_MICROFRONTEND_PORT:-2000}
	PORT=${LEARNING_MICROFRONTEND_PORT:-2010}

NIce! I have some open questions that I think should be called out in documentation for clarity, if they aren't already. If they are, could you please point me to them?

1. Where do I override this port if I want to set it to something other than 2010?
2. Do I have to manually run the update command to propagate all those port changes, or does this happen automatically every dev.up?

[ktyagiapphelix2u]

1. The source of truth is the LEARNING_MICROFRONTEND_PORT environment variable in devcontainer.json. To change it from 2010 to another value:

"containerEnv": {
    "DEVSTACK_WORKSPACE": "/workspaces/edx-repos",
    "LEARNING_MICROFRONTEND_PORT": "2000"  // Change this value to your desired port
},

You'll also need to update the corresponding entry in the forwardPorts array and portsAttributes section to match your new port.

2. The updateContentCommand runs automatically in these scenarios:

When the dev container is first created (postCreateCommand)
When you rebuild the container
When the [devcontainer.json] configuration changes

However, if you change the port in an existing running container, you'll need to either:

Rebuild the dev container (recommended - ensures all changes are applied)
Manually run [updateContentCommand.sh] to propagate the port changes to all the .env.development files
The manual approach would be:

./.devcontainer/updateContentCommand.sh
