fix(check): improve format of errors on multiple checks

[gacevicljubisa]

Idea of this PR is to improve output of errors, when multiple checks are executed.

Example output:

Error: CHECK_FAILED | 2/3 checks failed | Checks: ci-pss,pullsync | {"check":"ci-pss","time":"2025-03-03T13:11:27","error":"not implemented"} | {"check":"pullsync","time":"2025-03-03T13:11:27","error":"not implemented"}
