[BUG]: UseDotNet@2 task cannot find global,json on MacOS VMs

[prathikr]

New issue checklist

• I searched for existing GitHub issues
• I read pipeline troubleshooting guide
• I checked how to collect logs

Task name

UseDotNet@2

Task version

2.263.0

Issue Description

In our pipelines we checkout a second repo in addition to the current repo running the pipeline. On MacOS VMs we are observing failure in finding the global.json file which blocks our pipelines from running. It works fine on Windows/Linux, the issue is only present for MacOS. If you comment out the checkout of test-data-shared, the macos pipeline runs and there's no issue with the UseDotNet step. So something is happening before the UseDotNet@2 step runs that is affected by the checkout step even though it hasn't run it yet

Please advise on how we can resolve this issue, thanks!
