[FR] Align "Data Source" tags with MITRE

**Is your feature request related to a problem? Please describe.**
I feel like aligning the `Data Source` tags with the [MITRE Data Sources](https://attack.mitre.org/datasources/) suppliments
the existing MITRE ATT&CK mappings. Further building on an existing framework.

**Describe the solution you'd like**
Allow the `Data Source` tags to have the name of the sources mentioned in [MITRE](https://attack.mitre.org/datasources/).
E.g:
```
tags = ["Data Source: Container"]
```

**Describe alternatives you've considered**
Manually updating the definition file in our repository.

**Additional context**
I don't believe it should be 100% mapped. As in only those values should be allowed. But I do think the rules where possible
should have them tagged and custom rules should have the option.
