[SPARK-40116][R][INFRA] Pin Arrow version to 8.0.0 in AppVeyor

### What changes were proposed in this pull request?

This PR proposes to remoove the Arrow in AppVeyor for now to recover the build.

### Why are the changes needed?

SparkR does not support Arrow 9.0.0 ([SPARK-40114](https://issues.apache.org/jira/browse/SPARK-40114)) so the tests fail (https://ci.appveyor.com/project/HyukjinKwon/spark/builds/44490387)

Should recover the tests first because it looks it's going to take a while to add the Arrow 9.0.0 support.

### Does this PR introduce _any_ user-facing change?

No, dev-only.

### How was this patch tested?

CI in this PR should test it out.

Closes #37546 from HyukjinKwon/SPARK-40116.
