[uriparser] 3 of 6 public corpus downloads fail with HTTP status 403 — please help!

Hello, uriparser upstream here 👋

I'm running regression tests against the public OSS-Fuzz corpora in upstream CI (which works well in general, this workflow if curious). Unfortunately, of the six public corpora of OSS-Fuzz for uriparser…

• uri_dissect_query_malloc_fuzzer
• uri_dissect_query_mallocw_fuzzer
• uri_free_fuzzer
• uri_freew_fuzzer
• uri_parse_fuzzer
• uri_parsew_fuzzer

…only three can be downloaded successfully while the other three fail with HTTP status 403 for no apparent reason:

# for i in uri_{dissect_query_malloc,free,parse}{,w}_fuzzer; do xargs -t curl --head --silent <<<"https://storage.googleapis.com/uriparser-backup.clusterfuzz-external.appspot.com/corpus/libFuzzer/uriparser_${i}/public.zip" | head -n1 ; done

curl --head --silent https://storage.googleapis.com/uriparser-backup.clusterfuzz-external.appspot.com/corpus/libFuzzer/uriparser_uri_parsew_fuzzer/public.zip

Is there a chance that you could fix the permissions (or the download in general) of the other three corpus files to be truly public and unblock my pull request uriparser/uriparser#212 ? Thanks in advance!
