Provide a way to specify --syntax flag for stylelint

[efedorenko]

stylelint-staged detects syntax (i.e. SCSS) of committed files incorrectly — it throws errors that don't appear when stylelint is run normally. I'd guess that this is related to a new way that Stylelint requires syntax to be specified — it used to be defined in index.js, but now it is provided as param stylelint --syntax scss.

Does this seem related to the issue I was having yesterday?

Here is how syntax should be defined: https://github.com/stylelint/stylelint/blob/6b7fb87b67b964a8edf9c625aefbad9bfa2185c4/docs/user-guide/css-processors.md#parsing-non-standard-syntax

stylelint-staged does not specify --syntax when running stylelint in Shell script.

@derekrushforth yes, I think so.

The thing is, this styling-staged doesn't detect syntax at all. I need to find a way to provide it somehow.
