This issue is about setting up e2e tests for Web Terminal Operator that we would able to trigger as PR check, it would help make sure that proposed manifest changes does not break Web Terminal workflow.

So, in this test it would be nice to:

• build bundle and index images
• register custom catalog source
• install WebTerminal operator from there
• make sure Terminal button appears on OpenShift console after that
• test is it's possible to start and use workspace;
