Providing a more helpful message

Tried to validate a sbom using cyclonedx-cli command:
```
cyclonedx validate --input-format json --input-file /tmp/scan-trivy.cdx --fail-on-errors --input-version v1_4
```

What I expected: Invalid sboms should result in a clear and specific error message. (for example something like what [sbom-utility](https://github.com/CycloneDX/sbom-utility) prints)
```
[ERROR] invalid SBOM: schema errors found (/tmp/scan-trivy.cdx):

```
What happened: cyclonedx-cli output was not specific enough to identify the problem
```
Validating JSON BOM...
Validation failed:
