chore: move documentation responsibility to website

[wellwelwel]

Finally, the last step from website documentation 🌞✨

• All responsibility for documentation goes to the website.
• There are some intentionally duplicated sections (website and README.md):
  • History and Why MySQL2
  • Installation
  • Acknowledgements
  • Contributing
• No documentation has been changed, it's more about the README.md.

---

Changes

As mentioned in PR #2279, for this last step there are some changes.

Icons (Badges)

Removing unused badges from README.md:

• 
• 
• 

---

Nomenclatures

• node-mysql2, mysql2, Node MySQL2, Node MySQL 2 and MySQL 2 are now MySQL2.
• node-mysql, mysqljs and mysqljs/mysql are now Node MySQL and go to https://github.com/mysqljs/mysql every time.

mysqljs organization goes to https://github.com/mysqljs instead of the Node MySQL repository.

---

Sections

Documentation section (README.md) has been changed to:

Documentation

• Quickstart
  • First Query, Using Prepared Statements, Using Connection Pools and more.
• Documentation
• Examples
• FAQ

Dependencies

Firstly, I apologize for the large modification to website's package-lock.json.

Previously, I added the website's dependencies to dependabot check it weekly, but now I've changed it to daily.

Reason: avoid large amounts of PRs at the same time from dependabot, especially when combined to the main project's PRs.

That said, this is why I updated the website's dependencies manually this time.

Sorry for the long wait, I was enjoying some vacation time 🙋🏻‍♂️

[wellwelwel]

Due to the website's package-lock.json, I'll merge it to avoid new exhaustive PRs from dependabot.

@sidorares, please fell free to suggest and ask anything 🙋🏻‍♂️

Interesting simple topics could be:

• Icons / Badges such as tests and security status, etc. from master branch
• Change or add sections (or base it on some documentation you like)
• Traffic Insights (Google Tag Manager, for example)
• And anything you like (or that you don't like it either)
