Training and trainers - not pairing

[lawrenced]

The trainers are only showing one trainer for training that has two trainers. They are also not organising based on relevance.

The training should be like the following:

Training: Elixir Testing: From Zero to Hero with Devon Estes Trainer: Devon Estes

Training: From Zero To Hero With Elixir Trainer: Eric Meadows-Jönsson Trainer2: Andrea Leopardi

Training: Debugging A Running System with Ben Marx Trainer: Ben Marx Trainer2: Justin Schneck

Training: Getting up to speed with Phoenix and LiveView Trainer: Shankar Dhanasekaran

Training: Phoenix LiveView from Prototype to Production Trainer: Tam Kbeili Trainer2: Mike Martinson

Training: Ecto - From The Ground Up Trainer: Darin Wilson Trainer2: Wojtek Mach

This issue is in both the training box and on the training pages.

For the training box there is a file in _data/training.yml which in this case has to be edited manually since the type of design that has three columns per row ( one for the hours and the other two for each talk in that hour).

If you'd want the box to be dynamic and loop through the MD files in the _trainings folder we need to get rid of the third column and only keep the hours and one training per row.

I changed the structure of the training a little it looks like this now:

---
trainer: eric-meadows
trainer-2: andrea-leopardi
trainer-name: Eric Meadows
trainer-name-2: Andrea Leopardi
event_date: 28 April
venue: Centrum Konferencyjne, Golden Floor Tower, ul. Chłodna 51, 00-867 Warszawa
summary: This is an example of a description of the training
description: this is an example of the description about the training
experience: Beginner, Intermediate
from: 11.30 AM
to: 12.30 PM
type: training

Now it shows both names in the training layout, also added some logic to display the training link in each speaker or trainer related to the training.

It's not necessary to add two trainings even though the training has two trainers just need to add the correct file names and it will be filtered accord
