Adding a form section to the mobile version of the portfolio

[sinruidotec]

I am working on improving the portfolio project and its features.

In this Milestone:

• The pair programming modality is used to implement the required annexes to the portfolio.
• The form section with the required fields is added to the index.html file.
• The styles of the form are modified in the file styles.css.
• Stylelint errors fixed.

⚠️ I kindly ask you to take into account the errors that exist with the linters with which many people are having problems this week, I asked the community about them and they told me to send the project anyway 🙏🏼
