### Is your feature request related to a problem? Please describe It seems that directly adding Castopod Feeds to podcast players via RSS doesn't show transcripts added to the podcast. The SRT files are in the correct format and are even working with players such as VLC, but I believe that mobile applications are looking for https://podcastindex.org/namespace/1.0 instead of the current https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md I believe that the problems are with the mobile applications, but as a workaround, this is a request to change the namespace url. This request is to change the namespace from https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md to https://podcastindex.org/namespace/1.0 ### Describe the solution you'd like This request is to change the namespace from https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md to https://podcastindex.org/namespace/1.0 in the feed.xml generated ### Describe alternatives you've considered I can try to do a manual refactor locally to test, but haven't done it yet. I have tried multiple mobile apps that claim to support transcripts, but directly adding the RSS feed to the applications has never once resulted in the transcripts being loaded. Most recently the anytimeplayer.app mobile app gave the information that no transcript files were provided by the publisher (added directly via RSS from Castopod, not via a 3rd party site) even though the RSS feed xml data shows the transcript file as expected. https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md says the following ``` The namespace for this extension is https://podcastindex.org/namespace/1.0. Clients which recognize this namespace must also recognize https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md as identical. ``` But I suspect that mobile applications do not comply with this. ### Additional context If the podcast is server via a 3rd party index (not directly via Castopod), I have seen it display the transcript in one instance - Podverse does seem to present the transcript, but *only* if the transcript was present before the episode is published for the first time. In addition, the transcript seems to be partially hidden due to font size, but that's more likely a Podverse app issue.
