feat: fixed typescript error dynamic paths

[walid-mos]

Changes

Openapi-typescript creates an faulty file when using --path-params-as-types to generate types when nested path parameters exists.

This is particularly annoying when used with a Restful CRUD like :

• /users
• /users/{userId} ...

Hello, I drafted the PR because I thought there was a bug in my solution.

Finally I came across this observation, when you use a path that has a static part after the dynamic part, you have to add a / to make the typing work.

I don't know if that's likely to cause a problem, in my case it's fine, but I don't want to speak for other people.

Here's some example of what i am talking about :

without trailing slash:

any other path works fine
