Docs: Add steps to create issue and make screenshot of profile on the README

[adiati98]

Background

• We want contributors to learn how to create an issue as part of contributing flow.
• To prevent mistakes of not running the command to generate the profile, we want to ensure contributors providing a screenshot of their profile on the README after being generated to be included in their PRs.

Suggested solution

In the Getting Started section:

• [x] Add step 1 to create an issue.

1. Create an issue by clicking the "New issue" button in the "Issues" tab and complete the form.

• [x] Add a step to make a screenshot right after the step to "Run npm run contributors:generate in your terminal to generate the guest book on the README.".

X. Copy and paste the Markdown of the README in Markdown Live Preview and take a screenshot of your profile being generated. You will need this later when creating a pull request. Tips: If you don't see your profile in the "Contributors" section, zoom out the screen until you can see it before taking a screenshot.

• [x] Fix the numbering of the steps accordingly.
• [x] Check the code and the live preview format of the section. You can use Markdown Live Preview to live preview the Markdown.

Below is the code block of the "Getting Started" section:
