Add libicu (70) version in installdependencies.sh for Ubuntu 22.04 (linux/arm64)

[jacobfraer]

Describe the bug Currently there is no libicu version in installdependencies.sh for Ubuntu 22.04.

https://github.com/actions/runner/blob/users/tihuang/arm64/src/Misc/layoutbin/installdependencies.sh

To Reproduce Setup the runner on Ubuntu 22.04.

Expected behavior libicu70 should be installed on Ubuntu 22.04 by installdependencies.sh.

The script can install libicu-dev instead of attempting to install different versions of libicu or use a regex so that apt picks the correct version of libicu.

Runner Version and Platform 2.313.0 Linux/ARM64

OS of the machine running the runner? Ubuntu 22.04

What's not working? installdependencies.sh does not have libicu version for Ubuntu 22.04 which prevents the runner from starting.

This issue affects the newly-released Ubuntu 24.04 as well. Installing either libicu74 or libicu-dev satisfy the runner's .config.sh check for libicu.
