airflow/utils/email.py def send_mime_email doesn't take all values from connection

### Apache Airflow version

2.7.1

### What happened

When defining an SMTP connection only the user and password are taken from the connection. The host, port, starttls, start_ssl, from_email, timeout and retry are all taken from the configuration and not from the connection. Although the smtp provider (https://airflow.apache.org/docs/apache-airflow-providers-smtp/1.0.0/index.html) provides all these fields.

### What you think should happen instead

The following lines should be included in `airflow/utils/email.py` around line 246:

if conn_id is not None:
try:
from airflow.hooks.base import BaseHook

airflow_conn = BaseHook.get_connection(conn_id)
smtp_user = airflow_conn.login
smtp_password = airflow_conn.password
smtp_host = airflow_conn.host
smtp_port = airflow_conn.port

extra = json.loads(airflow_conn.extra)

smtp_starttls = not extra["disable_tls"]
smtp_timeout = int(extra["timeout"])
smtp_retry_limit = int(extra["retry_limit"])
smtp_ssl = not extra["disable_ssl"]

The from_email should be retrieved from the connection earlier in the call stack.

### How to reproduce

Install the SMTP provider:
pip install apache-airflow-providers-smtp

Create an SMTP connection in the UI
Set the `AIRFLOW__EMAIL__EMAIL_CONN_ID` environment variable to the connection id of the SMTP connection

Use the EmailOperator (`from airflow.operators.email import EmailOperator`) in a DAG.

Check the values that are used in send_mime_email.

Start in airflow/utils/email.py and trace the call from EmailOperator, including how AIRFLOW__EMAIL__EMAIL_CONN_ID reaches send_mime_email. Compare the SMTP provider's connection fields with the values currently read from configuration; done means the connection supplies the listed host, port, TLS, sender, timeout, and retry settings.
