Publish example documentation for using the PDK to create a RISC-V SoC

[mithro]

The SkyWater PDK documentation should include a full example of how to create a RISC-V SoC design using the OpenROAD ASIC tool flow.

I assume this should be assigned to someone from the OpenLane team?

@mithro OpenROAD can include example SoC designs once #5 is closed. Until then we can only demonstrate block-level designs.

For digital designers, this documentation would really help. @mithro Let me try playing with Open Road and seeing if I can come up with something.
