[Typescript-Angular] modelFileSuffix change dots '.' to slashes '/'

Created by: VincentSurelle

Description

I'm trying to generate typescript-angular api client with pet store sample. I installed openapi-generator with Homebrew and got version 3.3.3.

When I try to generate with modelFileSuffix='.model' with kebab-case my dot is changed to a slash. When I try to generate the same but with camelCase, it simply does not appear.

Here is a sample output :

openapi-generator version

3.3.3
