Mitigate deprecation/disablement warnings under Upload release asset workflow.

[kishen-v]

What happened:

1. There are few warnings reported under Upload release asset workflow, which are related to the usage of actions which are not maintained/publicly archived. The objective is to use suitable alternatives which are listed under the same archived actions/* repositories.
2. Usage of set-output command has been deprecated and is bound for disablement.

3. Usage of GH internal constructs : Build matrices to build for a combination of GOOS/GOARCH. Ref
