test(storage): cover GCS HTTPS OpenDAL TLS regression

[palkakrzysiek]

Follow-up to #6478. This keeps regression coverage for the OpenDAL GCS TLS feature by exercising Quickwit's OpendalStorage get_slice path against a local HTTPS GCS-like endpoint with TLS verification enabled.

Replaces #6479, which GitHub closed automatically after the temporary fix/gcs-opendal-tls base branch was deleted.

Local verification on commit 5de97a1:

• cargo check --features=postgres --tests --bin quickwit
• cargo check --features=postgres,metrics --tests --bin quickwit
• cargo nextest run --features=postgres,metrics --retries 1
• REST API tests against target/debug/quickwit
• cargo clippy --workspace --tests --all-features
• cargo deny check licenses
• cargo machete
• scripts/check_license_headers.sh
• cargo fmt --all -- --check
• git diff --check
• dd-rust-license-tool check
• cargo doc --no-deps
• cargo test -p quickwit-datafusion --tests
• cargo test -p quickwit-integration-tests --features datafusion metrics_distributed_tests -- --test-threads=1

Use supported OpenSSL validity options

When the documented regeneration script is run with OpenSSL 3.0.13, it exits before emitting any certificates because openssl req -help lists -days for generated certificate validity but does not accept -not_before/-not_after here; the redirected stderr makes the failure silent except for the nonzero exit. The same unsupported flags are used again for the server certificate below, so anyone trying to refresh the embedded test certs cannot reproduce them with the checked-in script.
