Pull request description:
When searching on Modrinth, also check slug directly
In Modrinth you can get the mod either by mod_id (site_id) or directly by slug,
as search results don't return any results when using the slug,

Fixes #135

### What changed?
- When searching on modrinth we not only search by `/mod?query=` but also check if we can find the mod directly by the slug on `/mod/slug`

### Testing
- [X] Added unit tests
- [X] Added integration tests
- [ ] ...Your own tests...

### Checklist
- [ ] I have reviewed my own code

### Related Issues
Fixes #135
