run --quiet CLI option outputs test steps

Current behavior

The cypress run --quiet CLI option does not suppress all Cypress stdout output. Test spec steps, such as the following, are output:

  template spec
    ✓ passes (421ms)

  1 passing (2s)

Desired behavior

According to cypress run Options, there should be no stdout output if --quiet or -q are passed:

Option	Description
`--quiet`, `-q`	If passed, Cypress output will not be printed to `stdout`. Only output from the configured Mocha reporter will print.

In a project with no Mocha reporter configured, running Cypress in a bash shell, the output from:

npx cypress run --quiet

and

npx cypress run > /dev/null

should be identical.

Test code to reproduce

Scaffold a Cypress E2E project with the single default cypress/e2e/spec.cy.js

describe('template spec', () => {
  it('passes', () => {
    cy.visit('https://example.cypress.io')
  })
})

Execute:

npx cypress run --quiet
