Pull request overview

This PR updates the package’s Azure Data Lake Storage (ADLS) access to use {azkit} for authentication, removing the previous {AzureAuth}-based token acquisition and simplifying the ADLS filesystem construction.

Changes:

• Replace managed-identity token acquisition via {AzureAuth} with azkit::get_auth_token() in get_adls_fs().
• Remove the local/emulator endpoint branch (LOCAL_STORAGE_*) from the ADLS filesystem setup.
• Update package dependencies to import {azkit} and add its GitHub remote.

note that this would likely have the same issue we saw in the outputs app, we would need to set the IMDS_AVAILABLE env var on connect to bypass the check for whether a managed token will work or not

Workflow error; looks like it needs to be redocumented.
