Since .NET dynamically loads libicu, it is not prone to ABI breakage and can load virtually any version. However, there is no `Depends: libicu*` option in Debian packages, so we need the explicit package version. This is prone to breaking as new Debian version bump the version number. This PR changes the `Depends:` to `Recommends:` so `libicu` is installed if possible, but does not prevent installation. For cases where the is no `libicu` on the system, there is now a `preinst` script which will warn if the library is missing, but not prevent installation. The warning should only show in Docker images or similar slim contexts, as `libicu` is otherwise installed with the base system.
