V3: [Go] Add exercises to config.json

[ErikSchierboom]

I've just noticed that the Go track has implemented Concept Exercises, but that they are not yet defined in the Go track's config.json file:

"exercises": {
    "concept": [],

Please add entries for the created Concept Exercises. For an example what each entry should look like, see this document or this example.

I can help with this. Just one question. Where do I find the uuid?

[SleeplessByte]

@oanaOM generate a new unique one for each exercise. For example:

https://duckduckgo.com/?q=uuid&atb=v184-1&ia=answer

[ErikSchierboom]

@oanaOM The default UUID generator that we usually use is https://www.uuidgenerator.net/version4, but any unique UUID would do.

Thanks everyone!
I've just submitted a PR with the updated config.json file.

Seems to be done
