test(core): assertTelemetry should accept partial metrics (aws#6477)

## Problem
assertTelemetry's docstring implies that it can expect partial metric
shapes but doing something like:
```
assertTelemetry('codewhisperer_userTriggerDecision', {
    codewhispererSuggestionState: 'Reject',
})
```
generates a type error. This is because it expects full metrics not
partial metrics

## Solution
Allow assertTelemetry to accept partial metrics
