Error Message: "Please install Az.Tools.Migration and make sure the version >= 1.1.5" on Extension Installation

There are no instructions in the documentation for how to properly install `Az.Tools.Migration` and ensure the version is >= 1.1.5. Additionally, if this requirement is not met, every time I open VSCode, I get an annoying notification saying that the extension has an error.

### Steps to Reproduce

1. Install the 'Azure PowerShell Tools' extension in VSCode.
2. Open VSCode.
3. Observe the error message in the output.

### Expected Behavior

The extension should provide clear instructions on how to install `Az.Tools.Migration` and ensure the version is >= 1.1.5. Additionally, the extension should handle the absence of this module more gracefully, without showing an annoying notification every time VSCode is opened.

### Actual Behavior

An error message is displayed, and there are no instructions on how to resolve it. The notification appears every time VSCode is opened, which is disruptive.

### Environment

- Visual Studio Code version: 1.96.0-insider 64-bit
- Azure PowerShell Tools Extension version: 0.3.0
- Operating System: Windows 64-bit

### Additional Context

Please provide detailed instructions in the documentation on how to install `Az.Tools.Migration` and ensure the version is >= 1.1.5. It would also be helpful if the extension could check for this requirement during installation and provide a one-time notification with instructions, rather than showing an error every time VSCode is opened.
