Fix GRPC IAST tests (#7485)

## Summary of changes

In a previous PR, we updated the [GRPC
sample](https://github.com/DataDog/dd-trace-dotnet/pull/7457/files#diff-a584760853efe2efa5b346a11c7a95486f1c9aa7700bcdfb97729eba34e23135).

This has affected the IAST tests, that use it. Since the code ownership
was not set to ASM, the previous PR passed.
This PR:
* Updates the snapshots of the IAST tests. The location of the
vulnerability has changed (line number, changing the hash of the
vulnerability) This particular sample has debug information, so line
numbers are taken into account.
* The ownership of the sample has changed to include security.
* Deleted debug info in test.

Where possible, please obtain 2 approvals prior to merging. Unless
CODEOWNERS specifies otherwise, for external teams it is typically best
to have one review from a team member, and one review from apm-dotnet.
Trivial changes do not require 2 reviews.

MergeQueue is NOT enabled in this repository. If you have write access
to the repo, the PR has 1-2 approvals (see above), and all of the
required checks have passed, you can use the Squash and Merge button to
