go update 1.21.6 from 2024-01-09 missing

[DavidS-ovm]

the latest builds of mcr.microsoft.com/devcontainers/go:dev-1.21-bookworm still contain go 1.21.5, missing the updates from go1.21.6

please ensure that minor versions get updated timely, as this makes devcontainers lag behind other automated updates like dependabot or renovate, breaking workspaces with

packages.Load error: err: exit status 1: stderr: go: go.work requires go >= 1.21.6 (running go 1.21.5)

For anyone else in the same situation, setting GOTOOLCHAIN to the required go version, or auto (see https://go.dev/doc/toolchain) downloads the required toolchain separately.

The latest go image released on 1/10 includes go version go1.21.6 linux/amd64

We push the new image to latest tag every month and sooner if there are major changes before that. If you would like to be on the bleeding edge of the image updates you may use the dev tag (example: mcr.microsoft.com/devcontainers/go:dev-1) of the images that we publish on a weekly or sooner cadence.
