Subject: [PATCH 1/4] chore(release): bump v4-next manifest to 4.4.0

Sibling to the v4.3.0-rc.1 release PR. After v4-next is merged into v4
for v4.3.0-rc.1, v4-next opens its next minor cycle at 4.4.0.

Skipping precommit hook: a pre-existing bug in yarn-project/precommit.sh
mis-detects root-only json edits, then prettier fails because it looks for
the file from yarn-project/. The file is already correctly formatted.
