[ic-time-input] Update spec tests

### Summary
Time input is a canary component and we haven't been able to run the tests for it due to issues with canary testing. However, after https://github.com/mi6/ic-ui-kit/pull/4150 it is possible to run `npm run test` in the canary-web-components package and it's showing that the time input tests don't all pass.

### 💬 Description
There are numerous time input tests that are failing (I think it's 9).

We need to get the test suite to run and all tests to pass so that we can add canary unit tests to the CI.

### 💰 Use value
We'll be able to run the canary unit tests.

In the canary-web-components package, first run `npm run test` and inspect the failing time input spec tests. Update the specs or related test setup so all time input tests pass, then confirm the package test suite is green and ready for canary unit tests in CI.
