fix: remove node_modules from built-in ignored dirs (#757)

Ignoring node_modules creates more issues than it solves. We use webpack watcher anyway, so ignoring these files or not will not affect watcher performance. User can always add node_modules to ignored dirs manually in webpack config.

Closes: #752
