Update scss/at-mixin-pattern

2

Hello, https://github.com/bjankord/stylelint-config-sass-guidelines/blob/ffa15c4106cbd75ea09327f4e8e10cc0be1379e6/index.js#L85 maybe prefer this regex: `"scss/at-mixin-pattern": "^[a-z]+(-?[a-z0-9]+)+$"` With that way mixins like `h1()` are possible and we can prevent mixins with multiple `-` like `foo--bar()`. Thanks
