Harmonize data type 'number'

[tenthe]

Body

Currently, the number data type serves both as a data type and a semantic type, causing inconsistency across the code base.

The PR #2616 initiated some harmonization steps, but there are still dual definitions for the number type:

• One in DataType (XSD:number)
• One in SemanticType (SO:number)

I propose supporting number solely as a data type and eliminating its role as a semantic type.
However, prior to making this change, it's crucial to assess which pipeline elements rely on number as a semantic type.
