V3: [Go] add links to existing exercises to reference

[tehsphinx]

Example Link to C# implementation: https://github.com/exercism/v3/blob/master/reference/types/number.md

Add links to the correct documents in the /reference folder (and subfolders) to the 3 existing Go exercise implementations:

• numbers
• basic-strings
• basic-slices

I can help with this.

@oanaOM: just ask here or on Slack if you have any questions!

Hey @tehsphinx ,couldn't find a reference to slices under https://github.com/exercism/v3/tree/master/reference/types. Is it ok if I just add it to the list?

[tehsphinx]

@oanaOM: You can add that and then we can ask for @ErikSchierboom and other peoples opinion in the PR. They might feel that we should link to e.g. list instead. We will see :)

[ErikSchierboom]

I'm fairly certain a slice is different from a list (although they can be used together), and yes: creating a new document under reference/types would be brilliant!

[oanaOM]

Sure thing. I've just added the slice.md under reference/types in my PR.

@oanaOM: Can this issue be closed or is there still something open?

[oanaOM]

@tehsphinx sorry for the delay response. All done for now, this can be closed.
