Use accessible links

[KevinWorkman]

I have a bad habit of writing sentences like this:

Click [here] to see the p5.js tutorials!

Unfortunately, these are bad for accessibility. If a screen reader user navigates over the links in the page, they'll hear a bunch of "here" announcements.

Instead, links should be formatted so they page they link to is in the text of the link, like this:

See [the p5.js tutorials] for more information!

If you see a "here" link, feel free to send a PR fixing it!
