Small update for filename in isle_integration.md (#5516)

Browse Source 
* Small update for filename in `isle_integration.md`

The name "clif.isle" is stale (since #4953), now two files "clif_lower.isle" and "clif_opt.isle" are generated. Not sure if that PR necessitates other changes this this doc.

* Update cranelift/docs/isle-integration.md
