Handle three gatsby-remark-prismjs warnings during build

Is this a desired choice? To have generic code blocks in gatsby-remark-prismjs?

When running "yarn dev" the three following warnings occurs.

warn unable to find prism language 'sh' for highlighting. applying generic code block
warn unable to find prism language 'jsxon' for highlighting. applying generic code block
warn unable to find prism language 'console' for highlighting. applying generic code block

These warnings can be prevented by adding one line in gatsby-config.js on line 86.

'gatsby-remark-use-jsx',
          {
            resolve: 'gatsby-remark-prismjs',
            options: {
              classPrefix: 'gatsby-code-',
              aliases: {sh: 'bash', jsxon: 'jsx', console: 'bash'}, < ---
            },
          },

But maybe we want to generic code blocks?

86行目付近の gatsby-config.js と、報告されている gatsby-remark-prismjs の警告を確認してください。"yarn dev" を実行して sh、jsxon、console の警告を確認し、その後、列挙されたエイリアスを追加することが意図された設定かどうかを判断して、警告が解消されたことを確認してください。
