Remove usage of archived module `github.com/pkg/errors`

[NitinRamesh25]

Currently github.com/pkg/errors is a direct dependency.
However this repository has already been archived for over a year.
Requesting to remove usage of this outdated library, as similar things have been done in other open-source modules.

Any update on this ?
It's only used in one place, to add stacktrace to the error instance.
Can't this simply be achieved using the runtime in-built module instead of relying on an outdated module github.com/pkg/errors
