Fix redirect test failure (only happening on macos)

[jbusecke]

When running the local rust tests I was getting:

ailures:

---- test_redirect_storage stdout ----
Error: ICError { kind: BadRedirect("Redirect Storage response must be a redirect, no location header detected"), context: SpanTrace [] }


failures:
    test_redirect_storage

test result: FAILED. 15 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 3.32s

error: test failed, to rerun pass `-p icechunk --test test_storage`
error: Recipe `test` failed on line 6 with exit code 101

Thanks to the suggestion of @li-em and some clauding I was able to fix this by replacing all occurences of localhost to 127.0.0.1 (apparently macos defaults to ::1).

I am going to dabble a bit with #1656 to see if I can actually expose the bug in CI before fixing it.

Since #1656 did not expose this issue I assume this is a behavior that was either changed after macos 15 or is somehow unique to my machine. So ill go to merge this anyways now.
