test: add unit tests for remove

[Shreya2005-2005]

Description

Adds unit tests for the remove() helper function in pkg/unikontainers/utils.go.
This function had no test coverage. The tests cover:

• removing the first element
• removing a middle element
• removing the only element

Related issues

• Fixes Add more unit tests #96

How was this tested?

Ran unit tests locally:
go test ./pkg/unikontainers/... -v -run TestRemove
All 3 test cases passed. Linter also passes locally (make lint).

LLM usage

Claude Sonnet 4.6 was used to assist in understanding the codebase and test structure. All code was reviewed and understood before submission.

Checklist

• I have read the contribution guide.
• The linter passes locally (make lint).
• The e2e tests of at least one tool pass locally.
• If LLMs were used: I have read the llm policy.

Hello @Shreya2005-2005 ,

there is no reason to test this function. It simple uses Go semantics. Also looking at remove we should replace it, having as reference https://go.dev/wiki/SliceTricks
