use Backus-Naur-Form for describing grammar for INTERFACE in endpoint

[BirgitBoss]

What?

“{interface-shortName}[-{serialisation-modifier-value}]-{interface-version}”*

should be Back-Naur as defined in Annex https://industrialdigitaltwin.io/aas-specifications/IDTA-01002/v3.1/annex/backus-naur-form.html

How?

<interface-shortName> ["-" <serialisation-modifier-value> ] "-" <interface-version>
