Detect lack of internet

[dcvz]

ATM if you try to do any internet bound command line tea -S and there's no internet connection tea will report its usual error screen:

panic: spilt tea. we’re sorry and we’ll fix it… but you have to report the bug!
    https://github.com/teaxyz/cli/issues/new?title=panic%3Aerror+sending+request+for+url+(https%3A%2F%2Fgithub.com%2Fteaxyz%2Fpantry%2Farchive%2Frefs%2Fheads%2Fmain.tar.gz)%3A+error+trying+to+connect%3A+dns+error%3A+failed+to+lookup+address+information%3A+nodename+nor+servname+provided%2C+or+not+known

TypeError: error sending request for url (https://github.com/teaxyz/pantry/archive/refs/heads/main.tar.gz): error trying to connect: dns error: failed to lookup address information: nodename nor servname provided, or not known

While any dev parsing this might easily realize what the issue is, it does invite the user to create an issue on Github. For a regular user it would save them and the tea team time by letting the user know the network is down and they should try again later.

@jhheider would it be possible to catch lack of internet connection and display an appropriate error message?

lack of internet connection is a complicated idea. all the software really knows is if an HTTP request has failed. i'd check and see what our current error message is, but i need my internet connection for the moment. ;)
