Fix infinite loop in wait_for_health() when container has no HEALTHCHECK configured

[mohityadav8]

Close #512

Overview

Fixes an issue where the wait_for_health() function could loop until timeout when a container has no HEALTHCHECK configured.

Problem

When a container does not define a HEALTHCHECK in its Dockerfile, Docker returns None for the health status.
The existing implementation did not handle this case, causing the loop to continue until the timeout was reached. This results in unnecessary waiting and incorrect behavior.

Solution

Added explicit handling for the None health status.
If health_status is None, the function immediately returns True, since the container has no healthcheck configured and waiting is unnecessary.

if health_status is None:
    return True:

The updated wait_for_health() function looks good 👍
We can also consider adding a test case for this in a follow up PR in future

Also, a small note: the Close #512 doesn’t seem to be linking correctly. You may want to move it outside the code block so it properly links to the issue. Thanks !
