fix(instrumentation-user-interaction): addEventListener throws when calling with useCapture = null

[t2t2]

Which problem is this PR solving?

When addEventListener is called with useCapture = null (technically against the spec but that stops nobody), event listener instrumentation throws and breaks apps

chrome:
TypeError: Cannot read properties of null (reading 'once')
    at addEventListenerPatched (https://tpmfzt.csb.app/node_modules/@opentelemetry/instrumentation-user-interaction/build/esm/instrumentation.js:180:66)

firefox:
useCapture is null
  at addEventListenerPatched@https://tpmfzt.csb.app/node_modules/@opentelemetry/instrumentation-user-interaction/build/esm/instrumentation.js:180:20

Repo: https://codesandbox.io/s/otel-user-interaction-event-capture-null-tpmfzt?file=/src/listener-null.js

Example of this error spotted in the wild: react-onclickoutside

Caused by typeof null === 'object'
