release: Bump main version to 8.5.0 (MetaMask#33460)

## Version Bump After Release

This PR bumps the main branch version from 8.4.0 to 8.5.0 after cutting
the release branch.

### Why this is needed:
- **Nightly builds**: Each nightly build needs to be one minor version
ahead of the current release candidate
- **Version conflicts**: Prevents conflicts between nightlies and
release candidates
- **Platform alignment**: Maintains version alignment between MetaMask
mobile and extension
- **Update systems**: Ensures nightlies are accepted by app stores and
browser update systems

### What changed:
- Version bumped from `8.4.0` to `8.5.0`
- Platform: `mobile`
- Files updated by `set-semvar-version.sh` script

### Next steps:
This PR should be **manually reviewed and merged by the release
manager** to maintain proper version flow.

### Related:
- Release version: 8.4.0
- Release branch: release/8.4.0
- Platform: mobile
- Test mode: false
