Fix urllib3 strict parameter warning

[action]

With oci v2.174.0 and urllib3 v2.7.0 we get an annoying FutureWarning hinting to us that the strict parameter is no longer needed.

Demonstrate Warning

Sample script:

$ cat warning.py
import oci

default_config = oci.config.from_file()
client = oci.object_storage.ObjectStorageClient(default_config)
try:
    client.list_buckets(compartment_id="foo", namespace_name="bar")
except oci.exceptions.ServiceError:
    pass

Result:

$ uv run warning.py
/home/akash/workspace/oci-python-sdk/.venv/lib/python3.12/site-packages/urllib3/poolmanager.py:329: FutureWarning: The 'strict' parameter is no longer needed on Python 3+. This will raise an error in urllib3 v3.0.
  warnings.warn(

Proposed Solution

In OCIHTTPAdapter we can delete the strict=True parameter, because we have been informed that it is no longer needed.
