Introduced `AdornmentAriaLabel` for better accessibility in the `MudField` component. Added `ShrinkLabel` parameter to control label display behavior. Created `FieldStartAdornmentTest` to validate `mud-shrink` class application. Updated `FieldTests` to include tests for new features and ensure correct field rendering with various adornment configurations.
- Restructured layout in FieldLabelPlaceholderExample.razor. - Updated ShrinkLabel feature in MudField. - Updated FieldPage.razor documentation for clarity on ShrinkLabel usage. - Modified FieldTests.cs to reflect new ShrinkLabel behavior. - Improved documentation comments for the ShrinkLabel parameter in MudField.razor.cs.

AdornmentAria was missing from MudField, added the property.
Added an override for ShrinkLabel behavior and updated documentation. This does not affect previous behavior, but allows someone using the MudField to force the label into Placeholder position by setting ShrinkLabel to true.
