We've decided to rename the default model and default inference endpoint for elser running EIS. This needs to be backported to 9.1 and 8.19 and we consider it as a bug as multiple other places (will) depend on these new names

Do we need to remove v from the text embedding and rerank default endpoint names too?

Nope, we'll only do the adjustment for ELSER to be en par with the ML node
