Steps to reproduce

What is expected?

Related to : #22122

The field rangePlaceholder: string[]; is missing.

What is actually happening?

Types of property 'timePickerLocale' are incompatible.
    Property 'rangePlaceholder' is missing in type '{ placeholder: string; }' but required in type '{ placeholder: string; rangePlaceholder: string[]; }'.ts(2719)
en_US.d.ts(44, 9): 'rangePlaceholder' is declared here.
