Postgres: Missing 12.1 and 12.1-alpine tags

[stevo-knievo]

Postgres 12.1 was released on the 14th of November 2019. Unfortunately, I can't find the tags for the 12.1 release on docker hub.
I saw the Dockerfile for version 12 got updated to 12.1-1.pgdg100+1. I deleted my local container image and pulled the latest container: docker pull postgres:latest. Then I ran the following command: SELECT version();

PostgreSQL 12.0 (Debian 12.0-2.pgdg100+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 8.3.0-6) 8.3.0, 64-bit

Mabey I do something wrong. Local container caching issue? I also tried removing all stopped containers: docker system prune -a.

I'm more than happy to do a PR to getting the tags online on docker hub. But unfortunately, I need a little bit assists.

Thanks in advance
