docs: stop documenting the e1000 NIC model as the default
The default NIC model for QEMU varies per machine type, and is liable to change across machine type versions. Documenting e1000 NIC as the default for PC/i386 is thus misleading to users at best. In particular the PC q35 machine type switched to use e1000e, but only in machine type versions after 2.11. Rather than try to explain which NIC model is used for each machine type version, remove mention of e1000 as the default, and steer users towards always specifying their desired model.
