Description

As per mdn/mdn#822, the Tools and setup section of the learning area is outdated and repeats content available elsewhere on MDN. It is also a maintenance burden — quite a few parts of it would be better updated so they point to the tool manufacturer's docs rather than us repeating it.

This PR updates the Tools and setup section to fix this problem. The following list provides notes on what I've done for each article in the section:

• What software do I need to build a website?: This stuff is covered in Installing basic software, so I've removed it and redirected to there.
• How much does it cost to do something on the web?: Some of this stuff was useful; I've put those bits in Publishing your website and deleted it and redirected to there. I also restructured the "Publishing your website" guide and updated the gh pages info there, pointing to GitHub's docs where appropriate and adding guidance in between. It's a shame there isn't one simple GitHub guide to follow to easily get something on gh-pages.
• What text editors are available?: Covered in Installing basic software. Deleted and redirected to there.
• What are browser developer tools?: This is still genuinely useful. I've copyedited it to improve the text and bring a few things up to date, and crunched the images a bit to reduce file size.
• How do you make sure your website works properly?: This is a bit of a strange mishmash of debugging tips. The bit about the network inspector and HTTP statuses was quite useful and not covered anywhere else, so I've added a brief network inspector section that covers it to What are browser developer tools?, then deleted it and redirected to there.
• How do you set up a local testing server?: This is genuinely useful and linked to in a few places. I've given it a copy edit and improved a few things.
• How do you upload files to a web server?: Another article that covers publishing web content. Again, consolidated, deleted, and redirected to Publishing your website
• How do I use GitHub Pages?: It is not worth us maintaining a separate page on github pages. I've deleted this and redirected to the Version control module page. I've made sure that page includes a prominent link to the gh pages step by step on "Publishing your website".
• How do you host your website on Google App Engine?: This was already deleted and redirected to the Google App Engine docs, so I've just removed the link from the section landing page.
• What tools are available to debug and improve website performance?: already removed and redirected to the relevant dev tools documentation, so I've just removed the link from the landing page.

There are only two articles left in the "Tools and setup" section now, so maybe a future PR could look at restructuring further.
