potiuk opened a new pull request, #38749:

In main we are using `uv` to build CI and PROD images to gain enormous speed
improvements. This helps with faster PR checks and iterations and lowers the CI
cost. However `uv` is not entirely stable yet and there are conditions that
make it fail sometimes (for example when old packages, not excluded by our
limits are published with wrong versions), also release imge is built with
`pip` and will continue to be built with `pip`. The gains for PROD iumage
builds with uv are much smaller than the ones for CI builds, so it's perfectly
fine to switch all `release branch` builds to use `pip` for PROD image builds -
we do not loose too much by doing it, but we gain stability.
