Schema-Automator incorrectly assigns dates to date-time type

[amc-corey-cox]

Describe the bug
With dates in the format 2024-01-22, Schema-Automator assigns the type to date-time in the schema. Validating the data with linkml validate causes the validation to fail because date-time should have the format 2024-01-22T00:00:00Z.

To Reproduce
Create a schema with dates in the 2024-01-22 format, then attempt to validate that data with linkml validate

Expected behavior
Schema-Automator should choose the more appropriate date range to allow validation

Additional context
Here is a quick sample file.
