feat: add `cyclonedx.model.dependency.Dependency.provides`

**Library Version:** `7.6.1`

**Description:**

**Steps to Reproduce:**
1. Use the example JSON provided in the [CycloneDX bom-examples repository](https://github.com/CycloneDX/bom-examples/blob/c0436d86cd60693f01d19fe1aacfd01e70e17036/CBOM/Example-With-Dependencies/bom.json).
2. Run the following script:

```python
import json
from cyclonedx.model.bom import Bom

# source: https://github.com/CycloneDX/bom-examples/blob/c0436d86cd60693f01d19fe1aacfd01e70e17036/CBOM/Example-With-Dependencies/bom.json

]
}'''

data = json.loads(sample)

Bom.from_json(data=data)
```

**Observed Behavior:**
The code fails with the following exception:

```
Traceback (most recent call last):
...
ValueError: Unexpected key provides/provides in data being serialized to cyclonedx.model.dependency.Dependency
```

**Environment:**
- Python version: `3.10`
- Operating System: `macOS`
- Library version: `7.6.1`

Let me know if this works!

Start at cyclonedx.model.dependency.Dependency and the Bom.from_json(data=data) entry point; inspect how dependency fields are deserialized. Add support for the provides field shown in the CycloneDX 1.6 example, then run the reproduction script and confirm Bom.from_json no longer raises the reported ValueError.
