feat: Add GoogleAnalytics 4 to frontend-platform

[UvgenGen]

Description:
alternative implementation for #471

Added support for GA4 to frontend-platform:

• implemented GoogleAnalyticsLoader class
• added loadExternalScripts function to inititalize.js
• Added tests for GoogleAnalyticsLoader.
• The Google Analytics ID can be configured in the edx-platform MFE_CONFIG settings:

MFE_CONFIG = {
    "GOOGLE_ANALYTICS_4_ID": "G-TEST"
}

or, the ID can be set in the frontend-platform .env file as:
GOOGLE_ANALYTICS_4_ID="G-TEST"

Merge checklist:

• Consider running your code modifications in the included example app within frontend-platform. This can be done by running npm start and opening http://localhost:8080.
• Consider testing your code modifications in another local micro-frontend using local aliases configured via the module.config.js file in frontend-build.
• Verify your commit title/body conforms to the conventional commits format (e.g., fix, feat) and is appropriate for your code change. Consider whether your code is a breaking change, and modify your commit accordingly.

Post merge:

• After the build finishes for the merged commit, verify the new release has been pushed to NPM.

I think we can just remove async from this function, yeah? We're not awaiting it where it's called, and it has no await keywords in it.

[davidjoy]

Gorgeous. 🤩

One tiny nit about an async keyword, but this looks great. I'm approving so you don't feel like you need a re-review, but I do think we should remove the async keyword from loadExternalScripts.

[UvgenGen]

@davidjoy Thank you) I removed the async keyword from loadExternalScripts and rebased PR

Sorry for the radio silence, I was off the last couple of days. This looks good to me as well, are any changes needed to openedx/edx-platform#32032 to support this? I'm not sure if I'm reading it wrong, but the reference to MFE_CONFIG here seems different from what's in there.

Also pinging @arbrandes since he was involved in the last solution, just to make sure I'm not missing anything we'd planned for there.

[UvgenGen]

@bmtcril no changes needed for edx-platform. We use two settings:

• GOOGLE_ANALYTICS_4_ID = "G-test" - for platform
• for MFE's:

MFE_CONFIG = {
    "GOOGLE_ANALYTICS_4_ID": "G-test"
}

[bmtcril]

Thanks for all of the work on this, Adolfo is away for a bit so I don't think there's any need to wait on his review. 👍

[arbrandes]

Looks good!
