Envoy Gateway: Help needed - Coverage build is failing after using `compile_native_go_fuzzer_v2`

After using the `compile_native_go_fuzzer_v2`, we encountered some issues with the fuzzing build. These were resolved using the suggestion provided here: [google/oss-fuzz#14190](https://github.com/google/oss-fuzz/issues/14190). Thanks for the help to resolve that! However, the coverage build is still failing.

Step #5: Failed to unpack the corpus for FuzzGatewayAPIToXDS. This usually means that corpus backup for a particular fuzz target does not exist. If a fuzz target was added in the last 24 hours, please wait one more day. Otherwise, something is wrong with the fuzz target or the infrastructure, and corpus pruning task does not finish successfully.

```

It appears that the coverage build is looking for a ZIP file for the corpus that does not exist.
We are currently using the `FuzzGatewayAPIToXDS_seed_corpus.zip` [naming pattern for the seed corpus file](https://github.com/envoyproxy/gateway/blob/2067f4cd3e418f245262719ad332862d4b144d04/test/fuzz/oss_fuzz_build.sh#L26), which previously worked without issues.

Looking for guidance on the possible cause of this problem.

Start with the referenced coverage build log and test/fuzz/oss_fuzz_build.sh, especially the seed-corpus naming pattern for FuzzGatewayAPIToXDS. Trace why coverage requests a different corpus path, then verify that the expected corpus is produced or located and that the coverage build completes successfully.
