fix(preset): recommended-bump ESLint preset (#295)

With commit 60815b5, it seems that the
Angular preset was inadvertently copied into the ESLint package.

This corrects the `conventional-recommended-bump` ESLint preset in
`conventional-changelog-eslint` to behave the same as the built-in
ESLint preset that was removed with #270.

Related to #241
