Update the I2C trait documentation in both embedded-hal and embedded-hal-async to clarify the NACK (No Acknowledge) behavior during read operations.
The previous wording suggested that a NACK was only sent for the last byte of the final read operation in a transaction. This has been corrected to specify that a NACK should be sent at the end of each read operation, whether it's followed by a stop condition or a repeated start condition.
This change ensures correct implementation of the I2C protocol across different scenarios and prevents potential communication errors.
