Foundation - Git - Add information about PRs and forks to session plan

[jesusoterogomez]

Main changes:

1. Updated session plan with two new sections:

• Pull Requests (reminder to explain creating, reviewing, merging PRs). Useful for the exercises.
• Forks

2. Breaks down exercise #1 into numbered steps

• The instructions for exercise 1 were written in a conversational format. This PR changes it to follow the format of the rest of the exercises with a numbered list. To make it easier to follow.
• Added a link to the README.md section of the hyf-assignment-template repo that explains how to create a PR to an own fork

Minor changes (unrelated):

• removed note about central/individual repo approaches (I assume this is outdated content)
• added small note about showing git add with all files vs. specific files. Trainees had issues with adding specific files during assignments due to not knowing they needed to type the entire path of the files.

I added this, but I don't think this is high priority during the session.

An explanation is already linked here:

Thanks for adding these changes 🙇

The linter is failing. If you run ./lint locally you'll be able to check yourself :)

After that, I'll approve and merge 🎉

Aww dang, I was SO sure I wasn't going to hit a linting issue. it's fixed now ✅

By the way, a super tiny detail:

Before running ./lint it seems we have to build the program at least once (npm run build) to get validateLinks.js in the dist directory

@jesusoterogomez haha it's a bet worth making.

Ah ok, I'll add it to the contributing guide at contributing/README.md, thanks for the heads up!

@adamblanchard
I'll get it right next time 🎰 💵

Also, I thought of that, but no need, I made this small edit to the linting script: #227
