fix: Update to `class-validator@0.13.2` generates `error TS7016: Could not find a declaration file for module 'validator'.`

Description

Updating a project from class-validator@0.13.1 to class-validator@0.13.2 generates 16 error TS7016: Could not find a declaration file for module 'validator'. messages on tsc transpilation when tsconfig.json is configured with the default skipLibCheck: false.

Minimal code-snippet showcasing the problem class-validator@0.13.2 removes @types/validator from the package.json dependencies, which now requires consuming applications to manually add @types/validator to avoid error TS7016 on transpilation when the default skipLibCheck: false.

Expected behavior

Update from 0.13.1 to 0.13.2 should allow project to build without error.

Actual behavior

Really don’t want to sticky my project to the previous version, any movement on this?

Fixes locally by npm i --save-dev @types/validator but it’s still a bug
