scriptsBlocked message is not intuitive

[luixxiul]

Describe the issue you encountered: scriptBlocked message, "Do you want to allow scripts on {{site}} from these sources?", is confusing and not intuitive.

It looks like as if they were origins which had been already allowed.

In that case I am not quite sure which origin will be actually allowed and denied (I can understand by thinking carefully, but not 100% sure).

• Brave Version (revision SHA): d9234b5

• Steps to reproduce: Open https://github.com, click the noScriptInfo icon

• Actual result: see above

• Expected result: I think the allowed origins should only be checked, which means that the noScriptInfo should be configuration dialog same as the site shield settings;

  allowed == checked 
  denied == unchecked
  

  For me that looks natural.
