feat(events): add form reset event

[pheeria]

Hi all!
This is my first PR to a popular OSS project.

What:

Forms have submit, but lack reset event.

Why:

Using form events instead of direct button callbacks comes handy sometimes, when using form templates with variable content.

How:

Events were extended to contain reset event applicable on <form /> tags.

Checklist:

• Documentation added to the docs site N/A (see below)
• I've prepared a PR for types targeting
  https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/testing-library__dom
• Tests
• Ready to be merged

Comments:

1. I think updating docs is not necessary since the following line covers everything.

Convenience methods for firing DOM events. Check out src/events.js for a full list as well as default eventProperties.

2. I can prepare a types PR if this one will be accepted.
