--cpu-count is a Windows-only option

[marckohlbrugge]

Kamal's docs mention a --cpu-count option here:

kamal-site/_docs/configuration.md

Lines 327 to 337 in 5901184

	job:
	hosts:
	- 192.168.0.3
	- 192.168.0.4
	cmd: bin/jobs
	options:
	cap-add: true
	cpu-count: 4
	```
	That'll start the job containers with `docker run ... --cap-add --cpu-count 4 ...`.

It took me a while to figure out why it didn't work for me. Turns out it's a Windows-only option:

--cpu-count CPU count (Windows only)

Source: https://docs.docker.com/engine/reference/commandline/container_run/#options

I think we should suggest the more universal --cpus option instead:

-cpus [API 1.25+](https://docker-docs.uclv.cu/engine/api/v1.25/) Number of CPUs

---

I'm new to Docker. I could be wrong. I'm also not sure if Kamal uses API 1.25+.
