oxcaml_effect rename to handled_effect causes checksum failure when installing oxcaml_effect

[venkatrao1]

https://github.com/oxcaml/opam-repository/blob/main/packages/oxcaml_effect/oxcaml_effect.v0.18~preview.130.76%2B222/opam#L27 contains the place to find the source archive for oxcaml_effect. However, that URL appears to now point to the renamed repo handled_effect. I think that the archive's sha has changed as a result of this rename (and I'm now getting an error when trying to install it as a dependency).

Dockerfile that I'm using, to reproduce this:

# Dockerfile for development/testing environment

# syntax=docker/dockerfile:1
FROM ocaml/opam:ubuntu-24.04

WORKDIR /home/opam

RUN DEBIAN_FRONTEND=noninteractive sudo apt-get update && sudo apt-get install -y autoconf

# OPAM docker image uses a local clone of repo by default, so update would do nothing unless updated
RUN opam repository set-url default https://opam.ocaml.org && opam update --all
RUN opam switch create 5.2.0+ox --repos ox=git+https://github.com/oxcaml/opam-repository.git,default
RUN eval $(opam env --switch 5.2.0+ox)

# from installation instructions for OxCaml
RUN opam install -y ocamlformat merlin ocaml-lsp-server utop parallel core_unix

I haven't used OPAM / OxCaml much before, so please forgive me if I've made a mistake somewhere in this process!

I also believe that this is causing the CI builds to fail: https://github.com/oxcaml/opam-repository/actions/runs/21035254443/job/60481247578#step:5:1500
