[bug] BTV plugin needs updating
## Bug Report
- [x] This is a bug report and I have read the contribution guidelines.


### Description
The location of the BTV livestream has moved to https://btvplus.bg/live/
**Edit**: Livestreaming no longer requires a user to login, so that can be removed from the plugin info page.


### Expected / Actual behavior
Streamlink should be able to handle the link.


### Reproduction steps / Explicit stream URLs to test
1. streamlink https://btvplus.bg/live/ best 
2. error: No plugin can handle URL: https://btvplus.bg/live/
