Discussed this PR during System Semconv WG 14/08/2025, and we noticed that if we agree on this rename, we should also agree on renaming system.netowrk.errors. In addition, this rename does not align with the system.netowrk.packets metric and the pluralization guidelines.

Moving to PR to draft for now.

Update: the system.network.errors does not need to be included in the packet namespace, it can include any errors received/transmitted by the network interface:

rx_errors
    Total number of bad packets received on this network device. This counter must include events counted by rx_length_errors, rx_crc_errors, rx_frame_errors and other errors not otherwise counted.
tx_errors
    Total number of transmit problems. This counter must include events counter by tx_aborted_errors, tx_carrier_errors, tx_fifo_errors, tx_heartbeat_errors, tx_window_errors and other errors not otherwise counted.

Moving back to review, renamed system.network.packets to system.network.packet.count so it complies with the pluralization guidelines.
