This patch prints out the cue file and line numbers when a cue error
contains multiple go errors to unwrap.
For example:
```
❯ holos render --cluster-name=k2 ~/workspace/holos-run/holos/docs/examples/platforms/reference/clusters/workload/...
3:31PM ERR could not execute version=0.46.0 err="could not decode: content: error in call to encoding/yaml.MarshalStream: incomplete value string (and 1 more errors)" loc=builder.go:212
content: error in call to encoding/yaml.MarshalStream: incomplete value string:
/home/jeff/workspace/holos-run/holos/docs/examples/schema.cue:199:11
/home/jeff/workspace/holos-run/holos/docs/examples/cue.mod/gen/external-secrets.io/externalsecret/v1beta1/types_gen.cue:83:14
```
