BUGFIX setup-skia-web script not picking up the custom folder param…

…eter (#2411)

After doing more testing with the `setup-skia-web` script, I realized that it wasn't picking up the custom folder parameter.
=> Just needed some parenthesis on the ternary condition to apply the proper value. 😬🤦🏼‍♂️

Use case: `yarn public/my/custom/path` should copy to the location specified in the first parameter.
