[BUG]: Azure devops task not respecting exclusion filters after build agent upgrade to 4.253.0

[cwatson-sd]

What happened?

After our Microsoft hosted build agent upgraded to 4.253.0, it stopped producing artifacts, and we traced it back to our DeleteFiles task no longer respecting the exclusion filters we added. We found that this was because the paths being constructed were adding a "." to the beginning of the exclusion paths.

For exact description of issue see this issue we opened in the azure-pipelines-tasks repo.

We believe it is because of the upgrade to Node 20 in 4.253.0 that included this change: nodejs/node@42d5821873?diff=split#diff-092f2be30e312ebf7517f3d5f08b4c8d38a4bea3449ab15eb87f408a8f301dff
