fix: use the correct delimiter value with nat-instance

[syphernl]

what

• Replaces var.delimiter with local.delimiter in nat-instance.tf

why

• After the changes done in Update to standard context, go mods, and GitHub config #97 creating a NAT instance is failing because it tries to do a replace on a null value

references

• Refs Update to standard context, go mods, and GitHub config #97

@syphernl Thanks for the contribution! Released as 0.29.0.

@Gowiem Thank you for reviewing and approving this PR.

Now that we are using auto-release, we are managing minor vs patch versions with labels. This PR should have been labeled "bug" or "bugfix" so that it would have been released as 0.28.1 instead of 0.29.0. You can also use the label "patch" for minor changes that are not exactly bug fixes. If the label does not exist on the repo, you can add it or as @cloudposse/engineering to add it. You can look at the labels on terraform-null-label as an example.

You can also use the "enhancement" label to highlight that the PR provides a significant new feature.

@Nuru Yeah makes sense, I botched this one. Thanks for pointing that out -- I'll keep it in mind moving forward.
