 - `ion-picker` and `ion-picker-column` have been renamed to `ion-picker-legacy` and `ion-picker-legacy-column`, respectively. This change was made to accommodate the new inline picker component while allowing developers to continue to use the legacy picker during this migration period.
   - Only the component names have been changed. Usages such as `ion-picker` or `IonPicker` should be changed to `ion-picker-legacy` and `IonPickerLegacy`, respectively.
   - Non-component usages such as `pickerController` or `useIonPicker` remain unchanged. The new picker displays inline with your page content and does not have equivalents for these non-component usages.
