Mac mini M4 CPU core count incorrect

[krokhale]

Description

I am running on the latest base model M4 Mac mini and I am noticing that the Maximum CPU cores that I can allocate is 8, I would expect it to be 10 based on the number of cores M4 has. Is this some sort of limitation/bug in Docker Desktop for Mac?

Note I am also using the latest Docker VMM.

xxx@gateway-mini ~ % sysctl -n hw.physicalcpu hw.logicalcpu
10
10
xxx@gateway-mini ~ %

Reproduce

1. Buy M4 Mac Mini.
2. Install Docker Desktop.
3. Look up the number of CPU's in Resources.

Expected behavior

I should see 10 cores.
