Make org.apache.jena.atlas.lib.Closeable extend java.lang.AutoCloseable

### Version

4.7.0

### Feature

By making `org.apache.jena.atlas.lib.Closeable` extend `java.lang.AutoCloseable` it will allow user to use _try-with-resources_ and enable detection by tools of missing `.close()`.

### Are you interested in contributing a solution yourself?

None

Start by locating the declaration of org.apache.jena.atlas.lib.Closeable and reading its current close contract. Confirm the public API change supports try-with-resources and that the relevant project checks pass; done means the interface extends java.lang.AutoCloseable without breaking existing usage.
