Check naming strategy in Spring Boot properties

[gytis]

Fixes #12483

[geoand]

@gytis CI seems to not like it :)

[geoand]

Also, this is breaking change so we will need to have something in the wiki

[gytis]

@geoand when and where do you want me to write an entry about the breaking change?

[geoand]

Just a note here and I'll copy it into the wiki.

This change replaces a hardcoded verbatim naming strategy of Spring Boot properties extension with the one defined in quarkus.arc.config-properties-default-naming-strategy property (kebab by default).

To keep your application operating as before, perform one of the following changes:

• Set quarkus.arc.config-properties-default-naming-strategy=verbatim in the application.(yml|properties)
• Replace the properties from verbatim style to kebab (default) or the one defined in quarkus.arc.config-properties-default-naming-strategy property.

The CI failure is completely unrelated ( quarkus-smallrye-graphql-deployment)
