feat: support ignoredPaths and redirectDefaultLanguageToRoot

[theowenyoung]

solve #53

Hi,

I just made a pr for adding ignoredPaths and redirectDefaultLanguageToRoot as an option for intl. Here is explain:

  {
    resolve: `gatsby-plugin-intl`,
    options: {
      // option for use / as defaultLangauge root path. if your defaultLanguage is `ko`, when `redirectDefaultLanguageToRoot` is true, then it will not generate `/ko/xxx` pages, instead of `/xxx`
      redirectDefaultLanguageToRoot: false,
      // paths that you don't want to genereate locale pages, example: ["/dashboard/","/test/**"], string format is from micromatch https://github.com/micromatch/micromatch
      ignoredPaths: [],
    },
  },

Can you review it or any advice?

@wiziple any concerns that you have here? Rather than keeping the fork it's best to stay united. This PR helps with SEO and should really be considered.
