test: update target flag tests for webpack 5.108 (#4797)

webpack 5.108 introduces the universal, deno and bun targets and
supports combining targets like node and web via universal ESM
output, which broke the target flag tests:

- update the "Unknown target" stderr snapshots to include the new
  universal, deno and bun entries
- replace the "should throw an error for incompatible multiple
  targets" test with "should allow multiple different targets",
  since node + web now builds successfully
- bump webpack to 5.108.3 in the lockfile so the snapshots match
  the installed version

Fixes the failing CI on #4792 and unblocks #4795.
