The `http get <url> <destfile>` utility had a bug with aria2c downloader where it couldn't properly save to destfile if it was an absolute path.
I have tried having `http get <url> -` output the downloaded file to stdout, but this conflicted with the output of `log_command` (which is also to stdout) so for now let's keep using the temporary file to resolve manual URL redirects.
TruffleRuby build definitions used to explicitly rely on `brew --prefix openssl@1.1` on macOS and abort installation if that was not found. However, this check didn't take into account that the user might have set OPENSSL_PREFIX in their environment, or that they have another `openssl@*` version installed via Homebrew. This change removes the `use_homebrew_openssl` check and allows TruffleRuby to perform its own OpenSSL detection.

* In TruffleRuby 23.1+, the GraalVM Updater (`gu`) is no longer available in GraalVM,
instead JVM Standalones and Maven artifacts are provided to replace `gu`.

truffleruby+graalvm-dev currently delivers builds using both the latest Java and the latest Java LTS release as a base. Since the latest Java changes more frequently than the LTS release, using the LTS as a base helps prevent the URLs from growing stale.
