Switch to Go 1.13 error wrapping (#604)

* Replaced errors.Wrap with fmt.Errorf (#589)

* Find:    errors\.Wrap\(([^,]+),\s+(["`][^"`]*)(["`])\)
  Replace: fmt.Errorf($2: %w$3, $1)

* Replaced errors.Wrapf with fmt.Errorf (#589)

* Find:    errors\.Wrapf\(([^,]+),\s+(["`][^"`]*)(["`])\)
  Replace: fmt.Errorf($2: %w$3, $1)
* Find:    errors\.Wrapf\(([^,]+),\s+(["`][^"`]*)(["`])(,[^)]+)\)
* Replace: fmt.Errorf($2: %w$3$4, $1)

* Replaced errors.Errorf with fmt.Errorf (#589)

* Find:    errors\.Errorf
  Replace: fmt.Errorf

* Cleaned up remaining imports

* Cleanup

* Regenerate provider support matrix

This was broken by #533 ... and it's now the third time this has been missed.
