Jacob Herrington 7d0aeeefe5 Improve the clarity of the docs and fix Prettier config (#4899)
* Improve format and clarity of the docs [ci skip]

While this change produces a lot of git noise by enacting what seems
like an arbitrary linewrap on most of the files in the documentation it
will result in better version control and tracking of the changes in the
documentation.

For example, as it currently stands, if one was to make a
PR to move a comma in a sentence because each paragraph in most of the
files is on a single line, that small change would look in the git
history like the author had modified the entire paragraph. In reality,
this author just moved a comma.

This change also includes a significant number of modifications to the
more article-esque docs. Many of these docs were written in a sort of
stream-of-conciousness and aren't as easy to read as they could be.
Hopefully this is the first of several readability changes. If we could
get these docs to a more accessible reading level, we would probably see
an increase in contributions. :)

* Delegate markdown wrapping to Prettier

* Add linewrapping explanation in the docs [ci skip]

# Code coverage
## Rails
Rspec will generate code coverage at the end of the tests.
To get the code coverage of the entire Rails codebase, you must run the full
Ruby test suite. You can run the full test suite with the `rspec` command:
```shell
bundle exec rspec
```
or
```shell
bin/rspec
```
To get the code coverage of a single file, you can run:
```shell
bundle exec rspec spec/models/user_spec.rb
```
or
```shell
bin/rspec spec/models/user_spec.rb
```
Once your tests have completed, the `coverage/index.html` will be regenerated
with some stats concerning the overall health of our test suite including a code
coverage metric.
To turn off coverage report generation please set environment variable
`COVERAGE` value to `false`.
## Preact
Preact tests will generate code coverage at the end of the tests.
To get the code coverage of the Preact codebase, you must run the full JS test
suite. You can run the full test suite with the npm task `test`:
```shell
npm run test
```
or
```shell
yarn test
```
Once the tests have completed, the test coverage metric will be visible in the
terminal window.
