Add account_host to extra fields in ADLS get_fs() method

[samuelkhtu]

Description

This PR addresses #53333 by adding support for the account_host field in the ADLS get_fs() method. The current implementation misses this field, even though it's commonly needed for custom Azure endpoint configurations.

What is the purpose of this change?

To ensure users can configure account_host via Airflow's Azure connection extras, aligning the behavior with other fields like account_name and account_key.

Backport

Please consider backporting this fix to the v2-10-stable branch. This bug affects users on Airflow 2.10 who rely on custom ADLS account_host values for enterprise or private Azure environments, and there is no workaround without this patch.
