gitlab-runner package metadata failing with signature issues

I'm seeing an issue this morning with downloading the latest gitlab-runner packages.

eg. for Ubuntu 22.04:

Hit:5 https://packages.gitlab.com/runner/gitlab-runner/ubuntu jammy InRelease
Err:5 https://packages.gitlab.com/runner/gitlab-runner/ubuntu jammy InRelease
  The following signatures were invalid: EXPKEYSIG 3F01618A51312F3F GitLab B.V. (package repository signing key) <packages@gitlab.com>

And for Rocky8:

Importing GPG key 0x6BA75A4E:

Is this ok [y/N]: y

and then trying again:
