BUG: Fuzzing check: OSS-Fuzz detection intermittent

[spencerschrock]

Describe the bug
The Fuzzing check intermittently fails to search the google/oss-fuzz repo. This is causing the check to fail at the CLI as well as the integration tests to fail.

• etc

Reproduction steps
Steps to reproduce the behavior:

1. scorecard --repo ossf/scorecard --checks Fuzzing --show-details --format json | jq
2. The reason string no longer mentions the project being fuzzed with OSSFuzz despite the project being fuzzed: link

Expected behavior

The project should detect OSSFuzz

Additional context

I think it's a problem with the code search API. The Fuzzing check makes a code search API request like the following:

curl \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer $GITHUB_AUTH_TOKEN"\
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/search/code?q=github.com+ossf+scorecard+repo:google/oss-fuzz

Using the search box on the website shows valid results.
