Invalid warning on quarkus.vault.secret-config-kv-path."prefix" property

[vsevel]

Describe the bug
Using property secret-config-kv-path."prefix" works as expected, but prints an invalid warning at startup:

WARN  [io.qua.config] (main) Unrecognized configuration key "quarkus.vault.secret-config-kv-path.singer" was provided; it will be ignored; verify that the dependency extension for this configuration is set or you did not make a typo

Expected behavior
There should be no warning

To Reproduce
Execute IT VaultMultiPathConfigITCase in the core project

Additional context
I am not sure if this is something that is specific to the vault configuration, because I don't see the same behavior on ConfiguredBeanTest that is using ConfiguredBeanTest with property public Map<String, List<String>> stringListMap with values:

# And list form
quarkus.rt.all-values.string-list-map.key1=value1,value2,value3
quarkus.rt.all-values.string-list-map.key2=value4,value5
quarkus.rt.all-values.string-list-map.key3=value6
