[INS-398] Added tests to ensure that custom endpoint configuration works in artifactory detectors

[MuneebUllahKhan222]

Description

This PR adds test coverage for both Artifactory detectors by introducing:

• 1 unit test
• 1 integration test

for each detector.

The tests explicitly configure detector endpoints using s.SetConfiguredEndpoints to ensure that:

• Detected secrets are validated against the intended configured endpoint

---

Purpose

• Improves confidence in detector behavior
• Ensures that the custom endpoint configuration works as expected in artifactory detectors.

Checklist:

• Tests passing (make test-community)?
• Lint passing (make lint this requires golangci-lint)?

---

Note

Low Risk
Low risk: changes are test-only and primarily add coverage around endpoint configuration and RawV2 construction for Artifactory detectors.

Overview
Adds new unit and integration tests for the artifactory and artifactoryreferencetoken detectors to validate custom endpoint configuration via SetConfiguredEndpoints.

The new tests assert that configured endpoints are included in Scanner.Endpoints() and that detection/verification builds RawV2 using the secret plus the configured endpoint (including URL trimming behavior for the reference-token detector).

There's something very "vanilla JS is all you need" about only using Go's builtin testing stuff, but we use testify all over the place and it simplifies things a lot, like you don't need things like:

got, err := s.FromData(ctx, true, data)
if err != nil {
  t.Fatalf("unexpected error from FromData: %v", err)
}

you can just do:

got, err := s.FromData(ctx, true, data)
// I usually leave the additional message off, but you do you
require.NoError(t, err, "unexpected error from FromData")

Oh also I meant to say I love starting w/ tests here! 🏆
