Since we download JS SDKs in a for loop which invokes a separate docker container for each `curl` run, we seem to be triggering some sort of a DoS protection. And rightfully so as the old method causes TCP and TLS churn although we advertise we support HTTP/1.1 and HTTP/2. This patch does a few things: 1. Uses `curl`s globbing support to download all files in one go, maxing TCP and TLS reuse. This should fix the DoS protection 2. Uses `curl`'s `--compress` option to make things even more efficient 3. Uses `curl`'s `--create-dirs` to save 1 docker container run per version for creating the directory 4. Removes the `-I` `HEAD` checks in favor of a `-f` fail option combined with `|| true` which makes curl fail and not write the output on a non-200 response while still allowing the script to succeed 5. To make sure the above approach works, it adds a file size test, requiring all downloaded files to be larger than 1kB
