Support Spring Boot v3

[rauldeheer]

Is your feature request related to a problem? Please describe.
I use Spring Boot v3 and I would like to use the Open API specification for my REST API.

Describe the solution you'd like
I would like for this package to support Spring Boot v3.

Describe alternatives you've considered
Downgrading to Spring Boot v2.x.x for now, but it is not worth the sacrifice.

Additional context
The exception I'm getting is:
