validate-commit-msg breaks on new version of validate-conventional-types

[hisabimbola]

validate-conventional-types just released a new version that includes additional commit types. This module is throwing errors when it's being used because it's not recognised. validate-conventional-types is being used in commitzen-cli.

The fix will be to fetch all commit types from validate-conventional-types module and not hard-code it as seen here

I will try to submit a PR for this

I just looked through the code and I saw that there is a feature to add load external module or dependency, I think that fixes this issue but since commitzen uses the module to load commit types, shouldn't this module do likewise, and make it the standard.

Sounds good. PRs welcome
