[Updatecli] Disable go mod updates

Let's consider disabling go mods update (except beats) from updatecli.

By removing `mods` from here:

https://github.com/elastic/cloudbeat/blob/456e24b2b660510380426621a485f7454ee7ece5/.github/workflows/updatecli.yml#L51

[Dependabot](https://github.com/elastic/cloudbeat/blob/main/.github/dependabot.yml) takes care of that and also groups updates in separate PRs (e.g., trivy, which needs more attention on each update), while with updatecli we have a single PR with multiple mods together ([example](https://github.com/elastic/cloudbeat/pull/2819/files)).

But we need to examine why sometimes dependabot workflow [fails](https://github.com/elastic/cloudbeat/actions/runs/12103193110).
