Linux collectors stop working after 1.5.8 upgrade

Describe the bug

After upgrade to 1.5.8 my linux collectors stopped working.

I see this debug messages for every collector run:

2026-08-29 16:10:08.167 DEBUG (MainThread) [custom_components.vserver_ssh_stats.ssh_collector] base collector command failed for malina.local: Remote collector exited with status 1
2026-08-29 16:10:08.310 DEBUG (MainThread) [custom_components.vserver_ssh_stats.ssh_collector] base collector command failed for malina.local: bash: line 1: powershell: command not found

2026-08-29 16:10:08.311 DEBUG (MainThread) [custom_components.vserver_ssh_stats.coordinator] Finished fetching malina data in 4.068 seconds (success: True)

As a result no value is collected at all.

I solved that by downrading to 1.5.7 for now and skipping 1.5.8 version.

Same here. After upgrading to 1.5.8, my Linux collectors broke with the exact same powershell: command not found error. I also had to downgrade to 1.5.7 for now to get things working again.
