Subject: [PATCH] fix: Pin playwright to base image version in `uv` Dockerfile
 template
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The uv branch previously kept whatever playwright version happened to be in
the env after `uv sync`, which can drift from the version baked into the
Apify base image — so the actor would look for a Chromium build that
`/pw-browsers/` doesn't ship. Snapshot the base image's playwright version
before `COPY`/`uv sync` and pin to it afterwards (mirroring the existing
sed-rewrite the pip and poetry branches use).
