Cells with `SLEEP_B` pins in `sky130_fd_sc_hvl` LV libs reference incorrect `related_power_pin` for them

[passant5]

SLEEP_B pin power should be in the range of 1.28V and 1.95V. it's related to VPWR which is 3.3V and it should be related to LVPWR as it is 1.8V. Only two cells have SLEEP_B pin: sky130_fd_sc_hvl__lsbuflv2hv_clkiso_hlkg_3 and sky130_fd_sc_hvl__lsbuflv2hv_isosrchvaon_1
