Warn the user & ask for confirmation when installing on untested OS verions

[someonemax]

Describe the bug
When installing on Ubuntu 24.04 there is no warning / request for confirmation that this version is untested.
Installing the script on this version results in HaProxy service not working.

To Reproduce
Steps to reproduce the behavior:

1. Install Ubuntu 24.04
2. Run: bash <(curl i.hiddify.com/release)

Expected behavior
The script should warn the user that their OS version is untested and might not work, and should ask for confirmation.
But it doesn't and will happily try to install the panel, which will be unsuccessful.
Because HaProxy service won't start on this version of the OS.

First of all, thank you for the report. Currently, I'm a little busy, but as you probably know, PRs are always welcome. If no one submits a PR, I will make the changes myself.
