fix(datetime): allow accurate typing of time values in 24-hour format

- Adjusted the `selectMultiColumn` logic to handle keyboard values like 20 and 22 dynamically.
- Introduced checks for the maximum column value to enable flexible input behavior.
- Added e2e tests to verify correct value selection for both 12-hour and 24-hour formats.

Closes ionic-team#28877
