Add "Still got questions?" section to about page

[mariana-caldas]

What do we need to build or fix? By considering the mockup guidelines (About Us V2) add the section "Still got questions?" just below the "Who we are" to the about page. This section works as division between the "Who we are" and the "Newsletter" we get from the Footer component.

Technical details

• git pull from main and create a branch feature/still-got-questions where to add the new implementation
• Use the component TwoColumn to implement the section -> https://github.com/Web-Dev-Path/web-dev-path/blob/main/components/containers/TwoColumn.js
• Link the CTA button to the contact us page

Deadline Please keep in mind that once you assign this task to yourself, you'll need to complete it in 7 days.

Acceptance criteria

• Test the section and components in many screen sizes, you can use the Inspect tool for that.
• Please test if the new changes added to the components do not affect the other instances.
• Test the feature in many browsers, such as Chrome, Firefox, Edge, and Safari (MAC).
• If there are any build problems when submitting your PR, run yarn build locally to solve the issues and commit the changes.
• Update the CHANGELOG.md file.
