fix: adjust alignment InlineRadioGroup component

[andreasfernandes93]

The uiForm.InlineRadioGroup component has an alignment issue due to the mt-2 class in its parent class. This causes a slight misalignment downwards compared to other form components that do not have this property.

Tests performed:

• I tried using the component inside a div with flexbox and another with grid, both with vertical alignment, but the issue persisted.
• I used the browser developer tools (Firefox and Chrome) to manually remove the mt-2 class and verified that the component was correctly aligned.

Expected behavior: The component should be aligned correctly with the other form components.
