Update quarkus.quartz.datasource documentation
### Describe the bug

The documentation https://github.com/quarkusio/quarkus/blob/main/extensions/quartz/runtime/src/main/java/io/quarkus/quartz/runtime/QuartzBuildTimeConfig.java#L46 is referring to `db` store which has long been deprecated and removed. 
We should update the javadoc to refer to `jdbc-tx` or `jdbc-cmt` job stores instead.

### Expected behavior

There is no mention of `db` store in the Quarkus documentation

### Actual behavior

`db` store is still mentioned

### How to Reproduce?

Go to https://quarkus.io/guides/quartz#quarkus-quartz_quarkus.quartz.datasource and observe the `db` in the description.
