[Fix] Refactoring calcolo versione CI/CD: usa git describe invece di dotnet msbuild

Problemi risolti:
- GitHub Windows: errore PowerShell 'Missing closing )' causato da (cd Dir; cmd)
  sintassi bash non valida in PowerShell
- GitHub Linux: versione 1.0.0 invece di 2.3.2 perche il tag v2.3.2 esiste solo
  su Gitea e non su GitHub, quindi MinVer trovava il vecchio tag v1.0.0

Soluzione:
- Sostituito dotnet msbuild -getProperty:Version con git describe --tags --abbrev=0
  che e lo strumento nativo Git per ottenere l'ultimo tag raggiungibile
- Funziona identicamente su Linux (bash) e Windows (PowerShell)
- Non richiede dotnet installato ne accesso al .git dentro Docker
- Rimosso il dotnet build intermedio sul runner (non piu necessario)
- Corretti i percorsi version.json: ora usa Data_Coupler/wwwroot/version.json
  dal root del repo invece di wwwroot/ relativo dopo cd

.gitea/workflows/docker-build.yml
