Add section for Go Trainers/Companies

[corylanou]

What are your thoughts on adding a section for Go Trainers?

Here are a couple I know of to start with, but I suspect it would grow:

Training Companies offering Go Workshops and Courses

• 353Solutions - Offers Go Workshops
• Ardan Labs Go Corporate & Individual - Specialized Training Solutions
• Gopher Guides - Go training in person and virtual with topics from beginner to advanced, profiling, web development, advanced testing, and more.

Having 3 or more items we can create a new category, we talk about it in the contribution guide.

@corylanou do you send PR with the change (update)?
