add support for Cypress component testing #620

from what I can tell based on the documentation and code it looks like only the e2e tests are being executed. I would like to use BrowserStack when running Cypress Component tests (see: https://docs.cypress.io/guides/component-testing/overview) which locally I can run using npx cypress run --component and by having a cypress.config.js file that looks like:

// cypress.config.js
const { defineConfig } = require('cypress');
const webpackConfig = require('./webpack.config.cjs');

module.exports = defineConfig({
    component: {
        devServer: {
            framework: 'react',
            bundler: 'webpack',
            webpackConfig
        },
        viewportWidth: 800
    }
});

NOTE: e2e test configuration could also exist in the above config file under a e2e key

I would like to be able to use the browserstack-cypress-cli tool to run component tests using a command-line option that indicates that component tests should be run and not e2e tests (it would be nice if there were several options available such as e2e as a default, component and both)
