upload.py failed because of invalid character in youtube description

Had a failure with Saturday Ballroom C for SCaLE 22x with Brian Honof's talk.

We've all probably encountered the following scenario at least once. We start pulling a container, and have to wait a solid 4–5 minutes... Why? Oh, our colleague decided to put all the development and building tools inside the container, making it >5 GB in size. Let me show you a way to construct images that prevent this from happening, and maybe teach you a thing or 2 about Nix in the process.' contains an invalid character. Modify JSON to include a valid youtube_description field.

It turns out that YouTube doesn't like the greater than or less than symbols. I don't know if there is an escape code for it, or we just have to spell it out as "greater than" and "less than".

Workaround was to update the JSON file to replace the ">" symbol.

Would like the upload.py to either automatically deal with it or be able to skip over it to upload the other talks and then report the talk that had the issue, so it can be fixed later.

The cutter tools use progress.json to keep track of what was successfully uploaded or not.
