This is not what we want to do, see comments.

You've misunderstood entirely what we want to do here.

We don't want to change the rule text, we want to change the license_expression for this rule to ms-net-library-2019-06 as this is a license we now have in licenseDB and so this is not an unknown license reference.

Note that we cannot just change a license-expression by replacing, we have to deprecate this rule and create a new rule, see the comment in #3744 (comment) for example. As this is reference data and we want to preserve these rule names and links to these.
