Allow organization / location to be user-specified

[sgbaird]

Update how the broadcast name is handled to allow for greater user customization:

streamingLambda/chalicelib/ytb_api_utils.py

Line 100 in 32e1ce8

broadcast_title = f"{workflow_name} stream @AC {cam_name}, {formatted_time}"

Doesn't matter so much immediately since these are only deployed within AC context, but will be necessary as others begin to implement. In particular, it's just the @AC that's problematic in this case. The rest can remain.

We could also probably remove this placeholder and instead suggest people to update the WORKFLOW_NAME from https://github.com/AccelerationConsortium/ac-training-lab/blob/main/src/ac_training_lab/picam/my_secrets_example.py as they see fit (e.g., appending the @ [organization] by themselves.

See AccelerationConsortium/ac-training-lab#432

Likewise see AccelerationConsortium/ac-training-lab#282

EDIT: will likely go with removing the placeholder, renaming WORKFLOW_NAME to YOUTUBE_TITLE_STEM or similar, and providing some instructions on naming conventions.

Also need to allow broadcast description to be customized, probably via BROADCAST_DESCRIPTION variable within my_secrets.py #2

😢 turns out this also renamed the playlists, and since the playlist names are based on those workflow names, it caused the issue. It would be a lot of manual work to try to move everything from the original playlists into this new playlist. Maybe I can rename the playlists..
