Summary

Fixed the following flaky specs:

1. Spec - spec/requests/internal_api/v1/team_members/details/update_spec.rb:

InternalApi::V1::TeamMembers::DetailsController::#update when Employee wants to update his own details is successful Failure/Error: expect(response).to have_http_status(:ok) expected the response to have status code :ok (200) but it was :unprocessable_entity ([42](https://github.com/saeloun/miru-web/actions/runs/3673181224/jobs/6212369080#step:20:43)2) # ./spec/requests/internal_api/v1/team_members/details/update_spec.rb:83:in block (3 levels) in <top (required)>'`

Problem was, in lastname param, we expect only alphabets and sometimes faker was adding ' in the string while generating last name

2. Spec - spec/requests/internal_api/v1/reports/time_entry/download_spec.rb
   Fix: Spec was not able to get document from the ES, added index refresh call.
