fix: narrow throws clauses in RetryTest to satisfy SpotBugs

Replace `throws Exception` with the actually-thrown checked exceptions
(`IOException, MinioException`, plus `InterruptedException` for tests
calling `MockWebServer.takeRequest()`). Drops `throws` entirely on
`testSetMaxRetriesValidation` since it throws only an unchecked
`IllegalArgumentException`.

Fixes spotbugsTest THROWS_METHOD_THROWS_CLAUSE_BASIC_EXCEPTION
findings on Java 8/11/17/21/25.
