Consolidate archiver/v3 and archiver/v4

[catsby]

Describe what should be investigated or refactored

We're using both archiver/v3 and archiver/v4, and we should just use one of them unless it's absolutely necessary to continue using v3.

As of Dec. 17th, 2024:

tasks.yaml
28:      - cmd: go list -f '{{.Version}}' -m github.com/mholt/archiver/v3

src/test/e2e/zarf_test.go
52:         args:        args{tool: "archiver", toolRepo: "github.com/mholt/archiver/v3"},

src/pkg/bundle/publish.go
17: av3 "github.com/mholt/archiver/v3"

src/pkg/bundle/tarball.go
21: av3 "github.com/mholt/archiver/v3"

It looks like src/pkg/bundle/tarball.go is the only file where they are both used:

uds-cli/src/pkg/bundle/tarball.go
