fix: errors being logged in json format when they shouldn't

before:

```
4:07PM DBG executing command cmd="/usr/local/go/bin/go mod why -m -vendor github.com/CycloneDX/cyclonedx-go" dir=/work
4:07PM DBG failed to initialize build cache at /.cache/go-build: mkdir /.cache: permission denied
{"level":"error","error":"failed to download modules: command `/usr/local/go/bin/go mod why -m -vendor github.com/CycloneDX/cyclonedx-go` failed: exit status 1","time":"2023-08-03T16:07:49Z"}
```

after:

```
4:05PM DBG executing command cmd="/usr/local/go/bin/go mod why -m -vendor github.com/CycloneDX/cyclonedx-go" dir=/work
4:05PM DBG failed to initialize build cache at /.cache/go-build: mkdir /.cache: permission denied
4:05PM ERR error="failed to download modules: command `/usr/local/go/bin/go mod why -m -vendor github.com/CycloneDX/cyclonedx-go` failed: exit status 1"
```
