Docker does not recognize 64bit kernel

I run my Raspberry Pi4 in 64 bit mode as you can see here:

$ uname -a
Linux jan-raspberry4 5.10.17-v8+ #1421 SMP PREEMPT Thu May 27 14:01:37 BST 2021 aarch64 GNU/Linux

When I try to pull an image which is for 64 bit available only, I receive this message:

$ docker pull gitlab/gitlab-runner
Using default tag: latest
latest: Pulling from gitlab/gitlab-runner
no matching manifest for linux/arm/v7 in the manifest list entries

What's going wrong here?

Your kernel is 64-bit, but your userland is not.

In 2020, Raspberry Pi OS launched a 64-bit beta and as far as I can tell, at the time of writing they are still in beta with known issues. The 64-bit builds can be downloaded from here:
https://downloads.raspberrypi.org/raspios_arm64/images/

If you're not comfortable running beta software, Ubuntu has stable 64-bit builds for the Raspberry Pi, as do a bunch of other Linux flavours.
