quarkus: Regression 3.3.0 config quarkus.config.locations with vault

Describe the bug

When switching from 3.2.4 to 3.3.0 , loading properties from vault does not work anymore when using quarkus.config.locations. It may apply to other config source extensions. Not sure at this point.

Expected behavior

property should be loaded from vault, as in 3.2.4

Actual behavior

the property is not loaded.

How to Reproduce?

create an application with quarkus 3.3.0 and vault extension 3.1.0 . start a vault like in the quickstart:

docker run --rm --cap-add=IPC_LOCK -e VAULT_ADDR=http://localhost:8200 -p 8200:8200 -d --name=dev-vault vault
docker logs dev-vault
...
# get Root Token: from the logs
docker exec -it dev-vault sh
...
# inside shell
export VAULT_TOKEN=...
vault kv put secret/myapps/vault-quickstart/config a-private-key=123456

in a directory somewhere outside the app:

• create a config directory
• create 2 files: application.properties and base-application.properties

in application.properties, add:

quarkus.config.locations=./config/base-application.properties

in base-application.properties, add:

config_ordinal=255

#quarkus.http.port=8090
quarkus.vault.kv-secret-engine-version=2

quarkus.vault.url=http://localhost:8200
quarkus.vault.tls.skip-verify=true
quarkus.vault.secret-config-kv-path.quickstart=myapps/vault-quickstart/config
quarkus.vault.authentication.client-token=<root token>
foo=${quickstart.a-private-key}

quickstart.a-private-key=xxx

quarkus.log.category."io.quarkus.vault".level=DEBUG

in GreetingResource:

    @ConfigProperty(name = "foo")
    String foo;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    @Path("/prop")
    public String helloProp() {
        return foo;
    }

start the application. you get:

$ java -Dquarkus.http.port=8090 -jar ../target/quarkus-app/quarkus-run.jar
Failed to load config value of type class java.lang.String for: foo

it works if:

• you switch to quarkus 3.2.4 and vault 3.0.0
• you add property quickstart.a-private-key=xxx to base-application.properties
• you move the content of basde-application.properties into application.properties
