formatParamUrl should be exposed

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

The formatParamUrl function HERE translates path in the fastify router format to openapi.
It would be great to have it exposed as decorator, so it could be used from the same purpose on other projects.

Motivation

I need to do exactly what this function does, but is not exposed from this module.

Example

Should it really be a decorator? And if you how name it?
Cant we just expose it to be requirable?

[mcollina]

We can also expose it to be requirable, it would work well for us too.

[Uzlopak]

I think exposing would be cleaner.

Yes, requirable is OK.
