Done as part of oncall improvements.
`vars.GO_VERSION` can only be changed by admins and it's not public
(Fleet devs don't know the current value of the variable), this approach
uses the version specified in our `go.mod` file.
#20571
## Summary of changes
We have a few moving parts in fleetctl land (`fleetdm/wix` is used to
build `msi`s and `fleetdm/bomutils` is used to build `pkg`s, and
`fleetdm/fleetctl` can be used to build packages using docker, no need
for fleetctl executable):
```mermaid
graph LR
fleetctl_exec[fleetctl<br>executable];
wix_image[fleetdm/wix<br>docker image];
bomutils_image[fleetdm/bomutils<br>docker image];
fleetctl_image[fleetdm/fleetctl<br>docker image];
fleetctl_exec -- uses --> wix_image;
fleetctl_image -- COPY dependencies<br>FROM --> wix_image;
fleetctl_exec -- uses --> bomutils_image;
fleetctl_image -- COPY dependencies<br>FROM --> bomutils_image;
```
So, we'll need to update the three images: `fleetdm/bomutils`,
`fleetdm/wix` & `fleetdm/fleetctl`.
- `tools/bomutils-docker/Dockerfile`, `tools/wix-docker/Dockerfile` and
`tools/fleetctl-docker/Dockerfile`: Updating the base image to fix the
CRITICAL vulnerabilities.
- Modified existing+unused
`.github/workflows/build-and-check-fleetctl-docker-and-deps.yml` to run
every day to check for CRITICAL vulnerabilities in `fleetdm/wix`,
`fleetdm/bomutils` and `fleetdm/fleetctl`.
- `.github/workflows/goreleaser-fleetctl-docker-deps.yaml`:
`fleetdm/bomutils` and `fleetdm/wix` were pushed manually a few years
ago (most likely by Zach), so I've added a new action to release them
when we have changes to release (like now). It will basically release
`fleetctl/bomutils` and `fleetdm/wix` when pushing a tag of the form
`fleetctl-docker-deps-*` (we'll need to protect such tag prefix).
- Changes in `.github/workflows/test-native-tooling-packaging.yml` to
build `fleetdm/bomutils` and `fleetdm/wix` for `fleetdm/fleetctl` to use
them instead of the ones in docker hub.
