rtlwifi: Update firmware for RTL8188EU to v28.0

It seems this fixes some issues with rtl8xxxu in monitor mode.

r8188eu from kernel 6.2.5 still works with this new firmware.

This firmware was extracted from the vendor driver v5.2.2.4 from
https://github.com/lwfinger/rtl8188eu/blob/v5.2.2.4/hal8188e_t_fw.c

Also, move the entry in WHENCE under the rtl8xxxu driver, because
that's the driver which handles this chip from kernel 6.3 onwards.
