Move bundle_report rails compatibility logic into a class (#137)
* Move bundle_report rails compatibility logic into a class I extracted it into a class because I think it will be easier to use the `incompatible_gems_by_state` data there. Based on the code review * Add incompatible with new compatible versions * Update changelog * Capture stdout to assert Co-authored-by: Ariel <ariel@ombulabs.com> --------- Co-authored-by: Ariel <ariel@ombulabs.com>
