TextMate uses libcurl (provided by Apple). I _think_ it uses the certificates in your keychain (OS X doesn’t include a CA bundle for curl by default).
You can try to manually hit the URL over https with /usr/bin/curl to see if that works. The URL for this would be https://api.textmate.org/releases/beta
