Currently, renovate will try to update to the latest patch release, i.e.
1.17.1 at the moment but the stable branches on github.com/cilium/cilium
don't contain the cilium-cli/ directory, thus breaking the build on
update PRs, see e.g. #2948

Instead, we should always be vendoring the latest version from main.
Drop the renovate configuration accordingly and instead update the
github.com/cilium/cilium dependency upon release of a new cilium-cli
version.

The only direct dependency in go.mod is github.com/cilium/cilium which
is updated manually before release (see
#2951).

The Go version in go.mod is already excluded from being updated by
renovate and because there are no other modules to update anymore we can
omit go.mod from being updated by renovate altogether.

Also remove some leftover configuration that no longer applies as a
result of the merge of cilium-cli into github.com/cilium/cilium.

- Partially revert commit cc1a61d [^1] since Cilium updated the Go
  version to 1.24 in main branch [^2].
- Change the default go-mod-directory to the top-level directory to
  match the current code structure in cilium/cilium where go.mod file
  is only in the top-level directory.
- Set setup-go cache-dependency-path parameter to '**/go.sum' so that
  caching works regardless of how go-mod-directory parameter is set.
