chore: remove dependency on "hashicorp/go-multierror" (#1322)

* feat: remove dependency on "hashicorp/go-multierror"

It seems the project has been unmainted for quite some time already,
see for example hashicorp/go-multierror#97
and hashicorp/go-multierror#98.
This also removes an uneccessary dependency which slims down the go.mod.

Go as of version 1.20 supports appending errors by specifying
multiple "%w" formatters in the "fmt.Errorf"[^0] function.

[^0]: https://pkg.go.dev/fmt#Errorf

* feat: use errors.Join to combine multiple errors

As an update to the previous commit 59f084e,
use "errors.Join"[^0] instead of multiple "%w" formatters for "fmt.Errorf".

[^0]: https://pkg.go.dev/errors#Join

* chore: bring back unused util.go file as removing it is a breaking change
