Don’t put the dontbemepodcast.rss file in your static folder. Anything in that folder doesn’t get processed by Hugo - it just gets copies, as is, into the public folder. (It’s the right place to put images, files etc., but not things you want processed by hugo).
I think you want to put the rss template into themes/dontbeme/layouts folder.
You also need to give the file an appropriate name so Hugo knows what to do with it. Have a look in the docs for ideas. But you probably want to name it index.xml (because on your site, the podcast feed is the only RSS feed you want to produce).
