    Fix transformer name normalization for catalog lookup during export (#23782)
    
    Transformer names use colon-separated format (e.g., 
aws2-ddb:application-json)
    but the catalog stores them in dash-separated format 
(aws2-ddb-application-json).
    Normalize the name before catalog lookup using the existing normalize() 
method.
    
    This fixes camel export failing with "Cannot find transformer with name:
    aws2-ddb:application-json. Did you mean: aws2-ddb-application-json" when
    exporting routes that use kamelets with data type transformers.
