test: hard code date values in Date_column_types_validation_spec (#36759

)

## Description
**Problem**
In the test spec, date data is fed directly from a file
`(app/client/cypress/fixtures/tableDateColumnTypes.ts)`, which includes
specific, static dates. However, the test is designed to handle relative
dates (e.g., "today" and "tomorrow"). As a result, when the date picker
opens, it displays a fixed date (e.g., September 2024), while the test
is attempting to select a date like October 8 (tomorrow’s date), which
is out of view.
