review and prune replace directives in go.mod

[arcolife]

Those replace directives in go.mod appear to be ever increasing, thereby increasing chances of conflicts when bumping up sub-dependencies.

For example, dropping back as much as 1.7.x -> v0.21.x for github.com/Azure/azure-sdk-for-go/sdk/azcore ..which might be justified for now, but we need to check all such directives.

This work needs a careful study of all such deps and their uses in the codebase, so as to prune them as per #4031 (comment) and #4031 (comment)
