Describe the bug
Crashes application when running in docker on alpine

To Reproduce
Steps to reproduce the behavior:

1. used getCpuCurrentSpeedSync()

Current Output
/app/node_modules/systeminformation/lib/cpu.js:1017
cores.push(parseFloat(speeds[i].toFixed(2)));
^

Environment (please complete the following information):

• systeminformation package version: 5.25.11
• OS: node:20-alpine
• Hardware: ARM CPU on in KVM VM inside Docker

To get all needed environment information, please run the following command:

Additional context
The function runs cat /proc/cpuinfo | grep "cpu MHz" | cut -d " " -f 3
This outputs nothing, so here is just the /proc/cpuinfo output
