This amends the blocking I2C example for embassy-rp. Commit bbc3e49 added a pull-up configuration and a comment that pull-ups were not enabled by default. This was made out-of-date by badcdcc, which ensured pull-ups were enabled by default to make the larger I2C configuration change non-breaking. This commit removes the (now-unnecessary) pull-up configuration, and adds a comment to clarify that the default I2C configuration enables pull-ups.
