What is the motivation for this change?

NODE-6008

Release Highlight

Deprecated unused CloseOptions interface

The CloseOptions interface was unintentionally made public and was only intended for use in the driver's internals. Due to recent refactoring (NODE-5915), this interface is no longer used in the driver. Since it was marked public, out of an abundance of caution we will not be removing it outside of a major version, but we have deprecated it and will be removing it in the next major version.

Double check the following

• Ran npm run check:lint script
• Self-review completed using the steps outlined here
• PR title follows the correct format: type(NODE-xxxx)[!]: description
  • Example: feat(NODE-1234)!: rewriting everything in coffeescript
• Changes are covered by tests
• New TODOs have a related JIRA ticket

@W-A-James Is the base branch for this PR correct? (CI didn't run because it's not pointing to main)

code changes are minimal and LGTM, but do we know what's going on with the Ci alias?

I didn't want to mark this as internal until we actually stop using it (once NODE-5915 is merged), so I pointed it at the branch with the changes that remove its usages.
