Update dependencies and fix some broken commands

[rebeccaalpert]

Updated dependencies so we don't have any entries in red anymore with npm outdated. I'm not sure if I should keep going, particularly with the PatternFly deps, but I did bump them somewhat. I updated Commander so I could link this with Core, which wasn't compatible with this older version when linked. This means that I had to change some of the bracketed text in https://github.com/patternfly/patternfly-a11y/pull/78/files#diff-180b3d2af89416b99563fff8c37eb8ca1ef7591fc1ddd736b5dacf740ccd3760R11, since it seems like spaces are no longer supported in square brackets.

New out of date listing:

I linked this to React and Core and tested against React and Core with every dependency bump, and made sure this builds.

I also noticed several commands were broken - I fixed yarn start and yarn test:pf. yarn test:org uses a port that I'm unsure we're still using, so I left that broken (want to ask some questions). I opened issues for two other broken commands.

At least partly fixes #73.
