fix: backport openedx-forum 0.4.1 to ulmo for thread sort bug

Bumps the `openedx-forum` pin from 0.3.8 to 0.4.1 on `release/ulmo`
to pull in the fix for the "pinned"-NULL sort bug
(openedx/forum#270, commit 78b36e4) where discussion threads were
not ordering correctly when users selected "recent first" — old
threads with NULL `pinned` values floated above newer threads.

Reported in:
https://discuss.openedx.org/t/discuss-forum-messages-order-not-organized-as-expected-in-teak/18665

The 0.3.8 -> 0.4.1 delta brings in:
  * 0.3.9 — five small bug fixes (Mongo content_type, timestamps,
    MySQL read_states lookup, Forum V2 author field, build).
  * 0.4.0 — MySQL backend query optimizations (N+1 fixes,
    prefetch/select_related); backwards compatible.
  * 0.4.1 — the `pinned` NULL sort fix (commit 78b36e4) plus the
    optional Typesense search backend (additive, off by default).

Caps openedx-forum at <=0.4.1 in constraints.txt to avoid:
  * 0.4.2 — drops Python 3.11 support.
  * 0.4.3 — removes the MongoDB backend (Ulmo deployments may rely on it).

The constraint should be removed on master / post-Ulmo release lines.
