Pull Request Overview

This PR updates the build automation vault endpoint to point at the newly created mobile build vault.

• Changed the BUILD_AUTOMATION_VAULT_BASE_PATH constant to the new URL.

Comments suppressed due to low confidence (1)

keyvault/src/main/java/com/microsoft/identity/internal/test/keyvault/ApiClient.java:76

• [nitpick] The constant name BUILD_AUTOMATION_VAULT_BASE_PATH no longer reflects the new 'mobilebuildvault' URL. Consider renaming it to something like MOBILE_BUILD_VAULT_BASE_PATH or MOBILE_BUILD_AUTOMATION_VAULT_BASE_PATH for clarity.

    public static final String BUILD_AUTOMATION_VAULT_BASE_PATH = "https://mobilebuildvault.vault.azure.net";
