While writing the documentation for the new Issn validator submitted yesterday at https://github.com/symfony/symfony/pull/7756, I've realized that the option ```requireHyphens``` should be renamed to ```requireHyphen``` because only one hyphen is allowed in the ISSN value.

This pull request addresses most of the issues regarding mime types and extension on File instances.

I've also created an issue on the docs to add more documentation about how things work (see symfony/symfony-docs#2542).
