test(amazonq): Add e2e tests for general amazon q chat panel

[jpinkney-aws]

Problem

• We want tests for the general amazon q panel
• We want other teams to quickly be able to write tests for their agents

Solution

• Add general tests for the amazon q chat panel
• Add a template that other teams can use to write their tests
• Fix an issue that occurred only in tests where tab id's weren't defined for the help message. The problem was that in the framework everything is instant which meant a tab id was defined before that code ran and was never passed through to processQuickActionCommand
• By default don't show the welcome page for now tests
