Add delaySnapshot env config

[tsirlucas]

Is your feature request related to a problem? Please describe.
I have similar problem you propose to solve using delay env config. But instead of waiting for an animation in the generated storybook, i want to wait a few ms before taking the snapshots. More specifically before cy.document() call.

Describe the solution you'd like
Basically following check before cy.document() call would do:

if (Cypress.env("delaySnapshot") {
cy.wait(Cypress.env("delaySnapshot"))
}

Describe alternatives you've considered
Currently I've patched the package and added it myself. I can open the PR if you guys want.

@tsirlucas thanks for the suggestion! If possible, we'd like to leverage the testing framework to help with this. Could this be accomplished by using cy.wait or another Cypress method to wait for an element in the relevant tests?

[tsirlucas]

yes its possible. in fact, its what i've done basically. it would be easier to have it as a config but im good with my workaround
