[Integration][CI] Conda Integration Test have started failing building integration testing rust

[raulcd]

Describe the bug, including details regarding any error messages, version, and platform.

Integration job have started failing when setting up the rust environment due to an old version of rustc being used:

   + pushd /arrow/rust
  /arrow/rust /
  + cargo build -p arrow-integration-testing --target-dir /build/rust

....
   error: package `half v2.5.0` cannot be built because it requires rustc 1.81 or newer, while the currently active rustc version is 1.77.2
  Either upgrade to rustc 1.81 or newer, or use
  cargo update half@2.5.0 --precise ver
  where `ver` is the latest version of `half` supporting rustc 1.77.2
  Error: `docker compose --file=/home/runner/work/arrow/arrow/docker-compose.yml run --rm -e ARCHERY_DEFAULT_BRANCH=main -e ARCHERY_INTEGRATION_WITH_GO=1 -e ARCHERY_INTEGRATION_WITH_JAVA=1 -e ARCHERY_INTEGRATION_WITH_NANOARROW=1 -e ARCHERY_INTEGRATION_WITH_RUST=1 conda-integration` exited with a non-zero exit code 101, see the process log above.

This is due to a dependency that was updated to require a new version of rustc. We hit the same thign in arrow-rs

• MSRV CI check is failing on main arrow-rs#7289

I think I have a workaround. I will make a proposed PR while we figure out what version of rust we can use
