We generally require a GitHub issue to be filed for all bug fixes and

- Closes #N/A.

## Rationale for this change

<!--
Why are you proposing this change? If this is already explained clearly
in the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand
your changes and offer better suggestions for fixes.

Please explain the problem you are trying to solve in terms of the
user-visible
behavior, rather than the implementation.

For example, "The code in `foo.rs` doesn't handle nulls" is a symptom of
the
implementation. "COUNT(DISTINCT) returns wrong results when the column
contains
nulls" is the user-visible problem.
-->

In commit #094ad31, @alamb fixed CI failure by temporarily ignoring the
two quick-xml RustSec advisories in the
audit workflow and documented that the ignores should be removed once
object_store upgrades to quick-xml >= 0.41.0.

Now that PR #25335 has been merged, we can remove these temeporary
ignores.



## What changes are included in this PR?

<!--
There is no need to duplicate the description in the issue here, but it
is sometimes worth providing a summary of the individual changes in this
PR.
-->

Remove the two temporary audit ignores in security_audit.sh. 

## What is the testing strategy for this PR?

<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code

Briefly describe how this PR is tested, and point to the specific tests
you added. For example: 'This new feature is covered by the
`sqllogictest` cases added in `foo.slt`'.

If this PR does not add tests, explain why. For example, if the change
is already covered by existing tests, please mention it.

You should also check the `codecov` bot reply on this PR to confirm the
changed code is exercised.
-->

Just CI update

## Are there any user-facing changes?

<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No
