`babelify` should not be removed when `.typescript` is set

• Operating System: Ubuntu 18.04
• Cypress Version: 6.1.0
• Browser Version: Chrome 87.0.4280.88

Is this a Feature or Bug?

This is a bug

Current behavior:

When .typescript option is set, babelify is removed from the transforms.
As a result, if the typescript file is dependent on a JS module using ES6, the transpilation will fail.

Desired behavior:

babelify should not be removed when using typescript as it may still be useful, as described here: #19

the line browserifyOptions.transform = transform.filter((stage) => !Array.isArray(stage) || !stage[0].includes('babelify')) should be changed accordingly

How to reproduce:

• write a typscript file with a depdency to a JS es6 module
• run the code

it crash
