Provide withExpandedAttribute prop to Select

[mariashipkova]

Combobox.Target has withExpandedAttribute prop that determines whether the target should have aria-expanded attribute.
Currently there is no way to add this attribute to Select component

Suggestion: https://github.com/mantinedev/mantine/blob/master/packages/@mantine/core/src/components/Select/Select.tsx#L266C6-L266C99

 <Combobox.Target targetType={searchable ? 'input' : 'button'} autoComplete={autoComplete} withExpandedAttribute={withExpandedAttribute}>
