pdm: fix "Volume" field

- Use ³ instead of the HTML entity form, ERP5JS does not allow HTML in field names
- Make Component_view uses Base_viewPDMFieldLibrary, like Product_view
- Add the proper description of this in field library
- Resource_viewFieldLibrary/my_base_volume is kept, for compatibility (not sure it's needed)
- Adjust ERP5Site_checkNamingConventions to allow m³, not m&179;
- Update all translations
