oci_compute_instance source_details.boot_volume_size_in_gbs break idempotency

[LCerebo]

Issue Report

If I specify the parameter source_details.boot_volume_size_in_gbs in oracle.oci.oci_compute_instance and run the task twice, the second time it breaks the idempotency giving a 500 Internal server error trying to update the resource.

"2024-11-13,11:58:26 DEBUG oci_log_utils.py:84 reply: 'HTTP/1.1 500 Internal Server Error\\r\\n'",

In the ansible debug log, launched with -vvvvvv I see the following lines:

"2024-11-13,11:58:26 DEBUG oci_common_utils.py:352 dict is not subset because attribute 'boot_volume_size_in_gbs' value in source does not match target",
"2024-11-13,11:58:26 DEBUG oci_resource_utils.py:936 is update necessary for instance: True",

Expected behavior

The expected behavior is to do nothing since no parameters are changed.
