Python: set openai package to newer version and removed default value of parallel tool calls (#10502)

### Motivation and Context

<!-- Thank you for your contribution to the semantic-kernel repo!
Please help reviewers and future users, providing the following
information:
  1. Why is this change required?
  2. What problem does it solve?
  3. What scenario does it contribute to?
  4. If it fixes an open issue, please link to the issue here.
-->
We noticed that the openai package dependency spec was off and did not
update that when present to the newest version, fixed now.
Also we mistakenly had a default value for parallel_tool_calls in our
prompt executions settings, as with other settings we do not maintain a
default value if the API has a default and in this case having that
parameter when calling a reasoning model threw an error, fixed here.
