Use non-canary credentials for AWS tests (#3109)
The AWS detector verifies credentials in a weird hacky way to work around some non-obvious STS behavior. This workaround does not work for canary tokens, so I updated the test secrets to use non-canary tokens. This PR updates the tests to match the secrets file changes.

// Our AWS detector interacts with AWS in an (expectedly) uncommon way that triggers some odd AWS behavior. (This odd
// behavior doesn't affect "normal" AWS use, so it's not really "broken" - it's just something that we have to work
// around.) The AWS detector code has a long comment explaining this in more detail, but the basic issue is that AWS STS
// is stateful, so the behavior of these tests can vary depending on which of them you run, and in which order. This
// particular test (TestAWS_FromChunk_InvalidValidReuseIDSequence) duplicates some logic in the "big" test table in the
// other test in this file, but extracting it in this way as well makes it fail more consistently when it's supposed to
// fail, which is why it's extracted.
