Feature reqest: expect.toMatch() to check is string matches RegExp

[mbyrne00]

Feature Request

Description: I would like to be able to use expect.toMatch(/test-string-[\w-]+/) with regular expression support. This is equivalent to expect("test-string-A4454556565").toMatch(/test-string-[\w-]+/)

Possible solution:
I can currently use expect.toSatisfy((src) => /test-string-[\w-]+/.test(src)); as a workaround but it would be nice for the API to support this out-of-box and also produce a more meaningful message when it fails.

Thanks for lib!
