Subject: [PATCH] fix(docker): add libicu* so PowerShell can start on Ubuntu
 26.04

.NET/PowerShell requires ICU for globalization. Without it, pwsh
aborts with "Couldn't find a valid ICU package". libicu* resolves
to the current runtime package (libicu78 on ubuntu:latest / 26.04)
and stays forward-compatible as Ubuntu advances.
