YAML align indent sizes for docs readability (#323)

This proposal has been aligned in a human readable.

    There are no changes to this except for spac
    The indentation size is not specifically defined in the YAML RFC
        $ make yaml has passed on my-machine

I set the indentation size to the largest number of articles in the repository (dictionary: 2)

(And also include nishigori as a CLA signer.)
