Prevent custom reaper image from causing Ryuk warning

[matthewmcnew]

• A custom provided ReaperImage would trigger the "Ryuk has been disabled for the container" warning when starting the Reaper image itself because the image name is used to detect if the container is the reaper container.

What does this PR do?

• This passes the selected ReaperImage as the ReaperImage when creating the Reaper ContainerRequest to ensure that it matches as the reaper image and prevents the incorrect warning.

Why is it important?

Configuring a custom ReaperImage currently leads to an inaccurate warning

	network, err := testcontainers.GenericNetwork(ctx, testcontainers.GenericNetworkRequest{
		NetworkRequest: testcontainers.NetworkRequest{
			Name:           networkName,
			CheckDuplicate: true,
			ReaperImage:    "some-other-reaper-image", 
		},
	})

=>

Hey @matthewmcnew thanks for this fix. Before merging it as is, could you please take a look at #647? It's still pending to be merged, and I think both PRs could be complementary

Other than that, this LGTM, pending the detection of possible conflicts with #647

Very much thank you for this!

Hi @mdelapenya Thanks for the heads up! it looks like #647 accomplishes what this PR is intending to accomplish. Happy to close this one if that one is merged 😄 .

As #647 was merged, and because of #720 (comment), I'm closing this PR.

Thanks @matthewmcnew for your time here and reviwing #647 👏
