feat(testing): support vite configOverrides for cypress

[TimvdEijnden]

We'd like to use shared cypress commands, but that's currently not working because vite cannot resolve the import.
By allowing to pass options to the vite config we have the possibility to add an alias or a plugin to fix this.

This adds support for an optional viteConfigOverrides object.

Current Behavior

cypress.config.ts:

import { nxE2EPreset } from '@nx/cypress/plugins/cypress-preset';
import { defineConfig } from 'cypress';

export default defineConfig({
  e2e: {
    ...nxE2EPreset(__filename, { cypressDir: 'cypress', bundler: 'vite' }),
  },
});

Expected Behavior

cypress.config.ts:

import { nxE2EPreset } from '@nx/cypress/plugins/cypress-preset';
import { defineConfig } from 'cypress';

const viteConfigOverrides = {
  resolve: {
    alias: {
      '@cypress-shared-commands': '../../../shared-cypress-commands',
    },
  },
};

export default defineConfig({
  e2e: {
    ...nxE2EPreset(__filename, { cypressDir: 'cypress', bundler: 'vite', viteConfigOverrides }),
  },
});
