File globbing not documented on site

[wzup]

How to configure it? This for example

By default, mocha looks for the glob ./test/.js and ./test/.coffee, so you may want to put your tests in test/ folder.

No any info in whole docs and wiki

Besides https://mochajs.org/#the-test-directory, there is https://mochajs.org/#usage:

Usage: mocha [debug] [options] [files]
(...list of options...)

However, I'm surprised that we don't have anywhere that the possibilities of globbing are highlighted, e.g. using lib/**/*.test.js. Even if we just pointed people at the glob NPM package for details on the supported syntaxes. (Although I think it would probably also be worth mentioning the pattern of putting files that need to run inside mocha.opts and then the default all-tests glob inside the test script in package.json so npm test runs all tests but mocha <path to specific file> runs only specific tests.)

I'm also surprised at the reference to Coffeescript -- I'm pretty sure that hasn't actually been part of the default for a long time... Clearly this whole section is long overdue for some TLC.

Site repo is at https://github.com/mochajs/mochajs.github.io, although we eventually want to get it merged into this repo...
