[CI] C# artifacts are currently rebuilt before deploying.

[sushantmimani]

Describe the bug
C# artifacts are currently rebuilt before deploying. Ideally, the artifacts built during CI should be deployed.

Expected behavior
The artifacts built during CI should be deployed without being rebuilt.

This is possibly being caused by the caching action itself and there are many such issue currently open. Will need to revisit this with a more robust caching solution
