10 Update Pre-Course module and HTML-CSS

[jason-vasilev]

Introduces the following changes:

1. Fix 404 Pre-course links in HTML-CSS
2. Language updates as renaming "homework" to "assignment", "lesson" to "session", "class" to "team"
3. Optimize graphic assets from from 3mb to 300kb by using https://squoosh.app/
4. Changed Session-exercise-template for Order form exercise to use index.html, styles.css, and removed empty id attributes, to set trainees on common good practices
5. Added detailed instructions to Order form exercise (The-one-and-only-week1/README.md) based on often-experienced pitfalls. Included link to video introduction to Figma.

Needs discussion:

1. Are the screenshots in first-assignment-submission.md still the process we want to follow? This is the split where trainees can either push PRs towards repo maintained by HYF, or towards the main branch of their own repo. We had quite some issues with team31 and 32 where we weren't merging their first PRs as they were towards a HYF repo.
2. Point 9 (previously 8) in first-assignment-submission.md might need changing from "post to Slack team channel" to "post to assignment sheet for this week"

Thanks so much for this @jason-vasilev! And for the language updates 🙇

Regarding your two discussion points:
The assignment review process we should be following is now defined in https://github.com/HackYourFuture-CPH/hyf-homework-template.

Regarding html-css assignment (ie. the first submission), @saloumeh-67 and I thought to remove the requirement to submit via github/pr, since the last teams had a lot of challenges regarding submission, which is not the point of this assignment.

I will raise another task, and write our previously planned idea there for feedback. We can make any changes after your PR here is merged, if that's cool with you.

Sounds good to me. Please, merge if there isn't anything that needs changing 🙂

p.s. sorry about the HTML-CSS/html-css issue, that was my bad. Thanks for fixing it!
