feat: allow plain http connections to s3

[sweb]

Description

@sbernauer and I noticed that http is supported by the native s3 integration of Trino afterall - their docs in 469 were just confusing to read and understand. This was since cleaned up in their documentation (see https://trino.io/docs/469/object-storage/file-system-s3.html#migration-from-legacy-s3-file-system vs. https://trino.io/docs/481/object-storage/file-system-s3.html#migration-from-legacy-s3-file-system) and this PR removes the gate for TLS.
