Update datamodel-code-generator requirement from <0.66,>=0.61 to >=0.61,<0.71

[dependabot]

Updates the requirements on datamodel-code-generator to permit the latest version.

Release notes

Sourced from datamodel-code-generator's releases.

0.70.0

Breaking Changes

• Preserved additionalProperties value constraints change generated output - JSON Schema additionalProperties (and propertyNames/mapping) value schemas that carry constraints (e.g. minimum/maximum, minLength/maxLength/pattern, array item constraints, allOf-merged primitives) now retain those constraints in the generated model instead of dropping them. This produces new TypeAlias/RootModel/TypeAliasType definitions and changes dict value type hints, so output differs for existing schemas. For example, a mapping value that previously generated dict[str, Literal['fixed']] now generates a dedicated alias preserving the constraints (#3616):

# Before
class DictModel(RootModel[dict[str, Literal['fixed']]]):
    root: dict[str, Literal['fixed']]
After
DictModelAdditionalProperty = TypeAliasType(
"DictModelAdditionalProperty",
Annotated[Literal['fixed'], Field(max_length=100, min_length=1)],
)
class DictModel(RootModel[dict[str, DictModelAdditionalProperty]]):
root: dict[str, DictModelAdditionalProperty]

0.69.0 - 2026-07-19

Breaking Changes

• Discriminated unions with duplicate or unresolvable discriminator values now fall back to a plain union - When a discriminated union contains variants that resolve to the same discriminator value, or variants that are containers, RootModel/type-alias wrappers, None/str members, or otherwise lack a resolvable discriminator literal, the generator no longer emits Field(..., discriminator='...') and instead produces a regular union. Previously such schemas emitted a discriminator= argument. Users regenerating models from these schemas will see the discriminator keyword removed from the affected fields (#3603)

# Before (invalid duplicate-value discriminator was emitted):
class GroupedItem(RootModel[Item | ItemReference]):
    root: Item | ItemReference = Field(..., discriminator='type')
After (falls back to a plain union when variants are not valid discriminated members):
</tr></table>
