doc: add dustThreshold explain of P2SH & P2TR

[jasonandjay]

The calculation of dust in Bitcoin has different values for different payment types.
For non-Witness: (148 + vout size)*rate
For Witness: (67+vout size)*rate

According to our calculation logic, our common P2PKH is 546, P2SH is 540, the minimum value of Witness is P2WPKH is 294, and P2TR is 330

However, the comments only mentioned P2PKH’s 546 and P2WPKH’s 294, which is inconsistent with the code logic.

These four payment types are very common in BTC wallets, so I think it is necessary to update the comments

Thanks for your interest in contributing, but this comment doesn't reflect what the code does (also see #22779 which is linked in a comment in the code). I think this could just be confusing?

I think comments should be consistent with the code
