Remove the github.com/pkg/errors dependency from the repo

Is your feature request related to a problem? Please describe.

github.com/pkg/errors The archive is no longer being updated, and std errors provides the ability to do so, so I want to remove github.com/pkg/errors and switch back to using the standard library.

What do you think? I will do this if you agree

std errors doesn't provide all the functionality of github.com/pkg/errors - particularly capturing a stack trace with an error. So I'd be against this for now.

From github.com/pkg/errors:

With the upcoming Go2 error proposals this package is moving into maintenance mode.

So it is maintenance mode, but waiting to be replaced by the Go2 proposal. So I would argue we shouldn't switch out until that lands.

Thank you

pkg/errors#245

errors has gone into read-only mode due to lack of new maintainers.

If we are currently relying on stack trace, then we can indeed wait a bit longer, as all the features have been largely implemented except for stack trace

Cleaning up as wontfix. We can revisit if the state of error management in Go changes.
