Remove deprecated Browserify Preprocessor

[artursopelnik]

Current behavior

Currently we are installing Webpack and also the deprecated Browserify preprocessor.

Desired behavior

Install only the Webpack preprocessor.

Removing "@cypress/browserify-preprocessor": "^3.0.2" from package.json

Background

The dependency "@cypress/browserify-preprocessor" install old and vulnerability dependencies

@cypress/browserify-preprocessor still has nearly 400k weekly downloads and is obviously still used, hence I am not removing support for it.

It is merely a peer dependency of this project and an optional peerdep even. If your package manager is installing it, it is doing something wrong (or you are), ref. npm/rfcs#221. In any case, you don't have to install it if you don't want to.
