v1.151.0 has no container images

### Description v1.151.0 is not on GHCR or on Docker Hub. Seems like [the CI job is failing because of some Element-internal infrastructure being broken](https://github.com/element-hq/synapse/actions/runs/24084625238/job/70253970968). ### Steps to reproduce `docker pull ghcr.io/element-hq/synapse:v1.151.0` ### Synapse Version v1.151.0
