MSAL: macOS native broker support

[TylerLeonhardt]

In theory, this is simply bumping the version of msal-node-extensions we depend on. It's not out yet, but it should be this week.

Looks like we're ready here: https://www.npmjs.com/package/@azure/msal-node-runtime?activeTab=code

we can pull in 1.5.19 https://www.npmjs.com/package/@azure/msal-node-extensions?activeTab=readme

Apparently to do this we'll need to add a bunch of redirect Uris (.helper is because it's coming from the Ext Host):

• msauth.com.msauth.unsignedapp://auth for local build
• msauth.com.microsoft.VSCode.helper://auth
• msauth.com.microsoft.VSCodeInsiders.helper://auth
• msauth.com.microsoft.VSCodeExploration.helper://auth

I got this from: https://learn.microsoft.com/en-us/entra/msal/python/advanced/macos-broker#usage the Linux page actually has a table:
https://learn.microsoft.com/en-us/entra/msal/python/advanced/linux-broker-py?tabs=ubuntudep#how-to-opt-in-to-use-broker

I know we have the Windows redirect Uri but might as well make sure we have the linux one:
