fix: drop network events once test runs to completion

[vigneshshanmugam]

• Addition to what we did on fix: avoid hanging on capturing network data #719
• Upstream bug in Chrome - https://bugs.chromium.org/p/chromium/issues/detail?id=1427331
• Avoid Waiting for all network events as its error prone and might hang the tests from getting closed forever when there are upstream bugs in browsers or Playwright. So we log and drop these events once the test run is completed
• Added a sig int handler to handle uncaught errors when not run in HB mode.
