Update public docs with new NAKS VM SKUs specs

New SKUs that will utilize the extra vCPUs on the new [Sapphire Rapids](https://en.wikipedia.org/wiki/Sapphire_Rapids) hardware will be introduced in the next release.

The new hardware supports 32 physical cores with 64 Hyperthreaded vCPUs. This enables support for larger VM sizes for NAKS worker nodes.

These new SKUs are:

- NC_G56_224_v1 (General Purpose SKU)
- NC_P54_224_v1 (Performance Optimized SKU)
- NC_E110_448_v1 (Cross-NUMA SKU)
- NC_E82_448_v1 (Cross-NUMA SKU)
