fix: pass chrome options to chromeOptions.addArguments()

[patsplat]

This PR should address #248

It updates 3 files to change how arguments are passed:

• Removes a now unnecessary cast from packages/cli/src/types.ts
• Changes how options are passed in packages/cli/src/lib/webdriver.ts
• Modifies test for option passing to match new behavior in packages/cli/src/lib/webdriver.test.ts
• Adds a test for multiple args in packages/cli/src/lib/webdriver.test.ts
