Refactor: src/setup/askForCustomPort/askForCustomPort.test.ts from Jest to Vitest

[palisadoes]

Is your feature request related to a problem? Please describe.
This file is currently tested using Jest. As part of our migration to Vitest, we need to refactor this file's test cases to align with Vitest's syntax and features.

Acceptance Criteria

1. Replace Jest-specific functions and mocks with Vitest equivalents
2. Rename the test file from having a .test.* suffix to a .spec.* suffix
3. Ensure all tests in the file pass after migration using npm run test:vitest
4. Maintain the test coverage for the file as 100% after migration
5. Upload a video or photo for this specific file coverage is 100% in the PR description

@palisadoes Want to take this up.

Our policy is to assign no more than two issues to each contributor across all repositories. This way everyone gets a chance to participate in the projects. We sometimes give exceptions for more urgent cases and sometimes we lose track, but the policy stands. You have reached your limit, please wait until your existing issues are closed before requesting more issues. You could unassign yourself from one of the other issues too.
