Feature/rfc 75

[mwmcode]

Trying to implement #75 (to the best of my knowledge/understanding).

I made shouldFail return array of violations instead of boolean.

shouldFail?: (violations: axe.Result[]) => axe.Result[];

Users can filter out the violations that they want to skip and only return the ones they want to assert against.

For example, I'm wrapping checkA11y to filter out color-contrast violations

Cypress.Commands.add(
  'customCheckA11y',
  { prevSubject: 'optional' },
  (subject, options, label) => {
    return cy.checkA11y({
      shouldFail: violations => violations.filter(v => v.id !== 'color-contrast')
    });
  }
);

Also

• updated dependencies
• upgraded cypress dependency to include v7
