feat: Allow opting out of default Chrome launch arguments

Related Issue - #430

Description

When Chrome is launched via Puppeteer, it automatically adds a set of default flags like --enable-automation --disable-extensions --disable-component-extensions-with-background-pages.

Currently, there is no way to opt out of these defaults, which makes certain use cases difficult or impossible to support. this PR adds a way to selectively ignore specific default Chrome launch flags applied by Puppeteer using its ignoreDefaultArgs property.
