Updating the handbook page to include more information about GitHub and Slack for new contributors

[santanainniss]

The Marketing Handbook page includes information about GitHub for new contributors.

Link: [https://make.wordpress.org/marketing/handbook/getting-involved/new-contributor-orientation/#managing-tasks-with-github]

This is the text from the handbook page:

The Marketing team uses GitHub for managing tasks and assets.

lab.github.com has several free courses available for learning. Courses that will be specifically helpful for contributing to this team are:

• Introduction to GitHub
• Communicating using Markdown
• Community starter kit

In creating this year's Contributor Day activities for WordCamp Asia, I identified that some helpful information was missing:

• How to sign up for a GitHub account
• How to find the Marketing team repository in GitHub

I'm going to to add these pieces of information to the Handbook page!

I have updated the handbook page to read:

The Marketing team uses GitHub for managing tasks and assets. If you do not have a GitHub account already, you can set one up by visiting https://github.com/login and following the account setup instructions.

Once you have an account with GitHub, you can find and join the Marketing Repository here at this link: https://github.com/WordPress/Marketing-Team.

Marketing tasks are typically divided into two types: Issues and Discussions. Discussions are most often used before an action has been decided on. Issues are created when a clear action is needed.

If you need additional training resources, lab.github.com has several free courses available for learning. Courses that will be specifically helpful for contributing to this team are:

• Introduction to GitHub • Communicating using Markdown • Community starter kit

I've updated the handbook even more:

1. Separated out the WP ID and Slack section
2. Made ordered lists for each section (WP, Slack, GH)

We are done editing the handbook for today. New edits can be part of a larger team convo and be on a new ticket.
