Bugfix CircleCI v2 throw error when fetching approval job

[Kesin11]

fix: #1120

CircleCI job detail API will fail with 404 when trying to fetch an approval job.
Previously CIAnalyzer would throw an error and stop when fetching this type of job. This PR fixes this problem by ignoring the approval job.
