Picky change to example justification in the spec

I feel like the statement

> The vulnerable code was removed with a custom patch

fits `vulnerable_code_not_present`:

> The vulnerable component is included in artifact, but the vulnerable code is not present. Typically, this case occurs when source code is configured or built in a way that excluded the vulnerable code.

better than `component_not_present`:

> The product is not affected by the vulnerability because the component is not included. The status justification may be used to preemptively inform product users who are seeking to understand a vulnerability that is widespread, receiving a lot of attention, or is in similar products.

The statement specifically states "vulnerable *code* was removed" via a patch. Rather than the whole component being removed.
