Merge branch 'fix/coverage-report-merge-time' into 'master'

Bump SimpleCov merge timeout to 365 days

## What does this MR do?

In case that CI pipeline fails because of intermittent errors in one of the jobs, when someone retries the only failing job located in the middle stage, the job that calculates compound coverage that is configured in later stage, and triggered after retrying job in the pipeline, will still return an accurate coverage value.

Closes #21144
