AAD Custom Authentication emulation settings are not compatible with the CLI

[shibayan]

Before filing this issue, please ensure you're using the latest CLI by running swa --version and comparing to the latest version on npm.

Are you accessing the CLI from the default port :4280 ?

• No, I am using a different port number (--port) and accessing the CLI from that port
• Yes, I am accessing the CLI from port :4280

Make sure you are accessing the URL printed in the console when running swa start!

ℹ️ NOTE: Make sure to enable debug logs when running any swa commands using --verbose=silly

Describe the bug

When using Entra ID (AAD) for SWA custom authentication, you must specify the format https://login.microsoftonline.com/<TENANT_ID>/v2.0 as openIdIssuer.

However, as far as I have tested, the SWA CLI emulation does not work correctly unless you specify the format https://login.microsoftonline.com/<TENANT_ID>/oauth2/v2.0.

#878

I think it is necessary to make the format of the openIdIssuer accepted by the SWA CLI consistent with that of SWA Cloud.
