ConfigProvider componentSize is not applied on Tabs component

[bn3t]

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

Encapsulate the tabs component with the ConfigProvider and specify componentSize other than the default (for instance 'large'). the Tabs component still appears as the default (not large) like it would with explicitly setting size="large" directly on it.

What is expected?

The Tabs component should follow configured component size in ConfigProvider. Tabs component should follow sizing like Input, Select and other components are doing.

What is actually happening?

The Tabs component does not modify its size. It is still necessary to set a prop size="large' for instance to modify its size to large.
