Fix live-reload failure for paths that include brackets

[hcgatewood]

Bug. Editing markdown files on paths with brackets/parenthesis (e.g. *Dropbox (Personal)*) causes the live-reload feature to fail. Fix. Update the chokidar dependency. This updates their is-glob dependency, which caused the issue. Tests. All tests pass locally. If someone wants to add a regression test that would be 👌🏻

See this previous discussion for more context.
