Azure Monitor Agent does not support Ubuntu 24.04

When installed on a vanilla Ubuntu 24.04 image, the deployment fails with the below error:

`[ExtensionOperationError] Non-zero exit code: 51, /var/lib/waagent/Microsoft.Azure.Monitor.AzureMonitorLinuxAgent-1.31.1/./shim.sh -install [stdout] Python 3.12.3 Importing utils failed with error: No module named 'imp' Unable to initialize waagent log because of exception name 'waagent' is not defined Info: Azure Monitoring Agent for Linux started to handle. Error: Unsupported operating system: ubuntu 24.04 Error: Unsupported operating system: ubuntu 24.04 [stderr] /var/lib/waagent/Microsoft.Azure.Monitor.AzureMonitorLinuxAgent-1.31.1/./agent.py:38: DeprecationWarning: 'crypt' is deprecated and slated for removal in Python 3.13 import crypt`

Start by reproducing the installation on a vanilla Ubuntu 24.04 image and inspect shim.sh and agent.py, including the reported Python import failure and operating-system check. Done means the Azure Monitor Agent installs successfully on Ubuntu 24.04 without the reported errors.
