fix(test): Fix flaky SpansSearchBar onSearch test

Consolidate multiple separate userEvent calls into a single
userEvent.type call with inline {enter} sequences. The separate calls
caused flaky timeouts because each convenience API call created a new
user-event session, losing focus context between the filter key entry
and value entry steps. Using a single type call keeps the interaction
in one session, matching the pattern used in the SearchQueryBuilder's
own test suite.
