fix(rule): Add required meta.fixable attribute

[DamienCassou]

Description

Eslint 8 requires adding a meta.fixable attribute to fixable rules: https://eslint.org/docs/8.0.0/user-guide/migrating-to-8.0.0#fixes

How has this been tested?

I have added the same change on my project which couldn't be upgraded to eslint 8 because of this.
