libicu dependency missing on Debian 13 (Trixie)

[lets-build-an-ocean]

The GitHub Actions runner fails to install libicu dependencies on Debian 13 (Trixie) because the installdependencies.sh script looks for older libicu package versions that don't exist in Debian 13's repositories. Debian 13 ships with libicu76, but the script cannot locate or install it.

To Reproduce
Steps to reproduce the behavior:

1. Set up a fresh Debian 13 (Trixie) system
2. Download and extract the GitHub Actions runner
3. Run ./config.sh --url https://github.com/YOUR-ORG/YOUR-REPO --token YOUR_TOKEN
4. See error: "Libicu's dependencies is missing for Dotnet Core 6.0"
5. Execute sudo ./bin/installdependencies.sh as instructed
6. Script fails to find/install libicu package

Expected behavior
The installdependencies.sh script should successfully detect and install the correct libicu package version available in Debian 13 (libicu76) and allow the runner to be configured without manual intervention.

For posterity,

I was running a Debian 13 server. I need to install the sudo apt install libicu-dev to have the latest version.

Just FYI.

You mean we can remove all libicu52 ... libicu76 and replace them with just libicu-dev?

[lewiechiu]

replace them with just libicu-dev?

Yes, that's what I found. IIUC maybe it's that libicu76 is included in the -dev so that's why it works.
