fix: use DAML release version instead of Canton internal version in Formula

- Updated Formula version from '3.4.0-snapshot.20250715.16432.0.vcd4fe703' to 'v3.4.0-snapshot.20250723.0'
- Fixed update script to use release.damlTag instead of release.cantonVersion for Formula version
- Corrected console messages to reflect DAML version usage
- Fixed Java version test assertion in Formula
- Ensures consistency with DAML ecosystem versioning
