error message displaying twice if signoz failed to install using install script

[nitishfy]

Bug description

When you try to self host SigNoz by using the install script, there are chances that you may come across certain errors due to which signoz might not get installed properly. Ideally, the error message should be displayed only once. However, the error message repeats twice.

It looks like the error message is being displayed twice due to the trap bye EXIT statement combined with the conditional checks later in the script.

Please describe.
