Use the initial version `1000`.
The generic setup profile version is usually influenced by the `setup.py` version, but it is not the same. Therefore we usually use a four-digit number here.

Examples:

| setup.py version | generic setup profile version |
| ---------------- | ----------------------------- |
| 1.0.0            | 1000                          |
| 1.0.1            | 1001, 1002, 1003              |
| 1.0.2            | 1004                          |
| 1.1.0            | 1100                          |
| 2.3.5            | 2300                          |
