Feedback on page "Switch Expressions (JEP 361)"

[veselin-vasilev]

Hello, I would like to propose the following improvement on this page:

All of the suggestions go under the "The Four Forms of Switch":

1. The second bullet point is cut short after "unless'. I assume it was supposed to finish with "explicitly terminated with a 'break'."
2. The first example in this section is for a switch statement without fall through. However, it showcases a switch expression. I think this was likely a copy-paste issue, as this example has the same code as the example preceding it in the previous section ("Statements in Branches").
3. The second example in this section is for a fall through version of switch expressions, but it includes a yield in every case, thus not actually demonstrating the fall through.

Since these are fairly trivial to fix, I've raised a PR for it. GitHub doesn't seem to have automatically linked the PR, so here it is -> #61
