[CI][R] AMD64 Windows R release fails with IOError: Bucket 'ursa-labs-r-test' not found

[raulcd]

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

In the AMD64 Windows R release I am finding that an S3 tst fails due to a missing bucket, I don't think this is related to my PR:

══ Failed tests ════════════════════════════════════════════════════════════════

@thisisnic have you seen this previously?

Seems to be failing for C++ too on some scenarios but not all ARM64 Ubuntu 22.04 C++:

 [ RUN ] S3RegionResolutionTest.RestrictedBucket
/arrow/cpp/src/arrow/filesystem/s3fs_test.cc:435: Failure
Failed
'_error_or_value41.status()' failed with IOError: Bucket 'ursa-labs-r-test' not found
[ FAILED ] S3RegionResolutionTest.RestrictedBucket (88 ms)

ok, it seems to be failing on other PRs like (#49608) too so not my PR :)

This is new. Also strange as I thought I'd migrated the tests to the new S3 stuff - I guess I missed those, sorry!

(Other PR is #48260 - looks like I didn't get the Ursa ones there)
