aligned KAKUTEH7WING target with manufacturer docs

[paulwrath1223]

Super simple fix for this issue.

!! This risks breaking older builds that attached sensors to the FC in accordance with the iNav target and not the manufacturer docs !!

The Kakute H743 Wing target in iNav lists the Pitot sensor as being on I2C bus 1, but HolyBro says to use I2C bus 2.

Manufacturer Manual says I2C bus 1 is just for compass, and other peripherals should use I2C bus 2.

Also the wiring diagram uses I2C bus 2:

This PR just changed the pitot, rangefinder, and external temp sensors to I2C bus 2

Paul, I believe you said you tested this with a pitot in the external i2c plug, labeled i2c 2. Correct?

Note - the key line in the manual is probably:
3x I2C (I2C1 and I2C2 for external devices , I2C4 for onboard sensors )

@DzikuVx Our I2C1 is designed to be use with our GPS+Compass, so I think it make sense to make this change.

Can we add a remark to what sensors go in which i2c bus/plug to docs/boards/KAKUTEH7WING.md ?

There currently isn't a doc file for this board. I don't mind making one, now that I have the board and know the system better than I wanted to, but should I put it in a separate PR?

NVM, Thanks @sensei-hacker

Yes. I flashed the firmware with this change and confirmed it works as I would expect. (With I2C 1 only working for the included mag and the unused plug for other peripherals) I only have a pitot and mag, so I was unable to test the external temperature and rangefinder changes, but I can't imagine they will behave any differently.
