Description of problem:
When the user uses the Web terminal operator and something fails, the terminal panel shows an error. At the moment this happens also if the user tries to close the terminal with `exit`. This issue is tracked here: https://bugzilla.redhat.com/show_bug.cgi?id=2110541

But whenever the terminal shows an error, the user might want close this panel.

The UI asks now the user "Close terminal?"

This is confusing at this terminal is already broken.

Version-Release number of selected component (if applicable):
4.10+

Tested this on the Developer Sandbox. Might exist also on older versions.

How reproducible:
Always

Steps to Reproduce:
1. Install Web Terminal operator or test it on the OpenShift Developer sandbox.
2. Open the "Command line terminal" with the button in the main navigation
3. Type `exit` (at least until https://bugzilla.redhat.com/show_bug.cgi?id=2110541 is fixed) , found another way do break the connection
4. The terminal should show an error "The terminal connection has closed." and a reconnect button
5. When the user now closes the panel with this error...

Actual results:
A modal asks the user if this is really intended.

Expected results:
The user should not be asked if it is really his intention if the panel shows already an error.
