Update meta.yaml

We have updated one of the dependencies of the `arborator` package, `genomics_address_service`, to version [0.1.3](bioconda#53618) to fix a bug. While `arborator` will work with older versions of `genomic_address_service`, I would like the container on biocontainers to be updated to include the most recent version of `genomic_address_service`. This PR updates the build number in order to trigger a re-build of the container.
