VSKit - description newline replacement

[plbremer]

VSKit generates "descriptions" for LinkML from ontologies. Sometimes, those descriptions contain newline characters. These newline characters break downstream LinkML tooling such as the Pydantic generator.

I believe that it is appropriate to replace those newline characters with spaces at this point in the flow.

An example of this newline phenomenon is the permissible value IP-seq from EFO:

      IP-seq:
        text: IP-seq
        description: "IP-seq is an assay in which immunoprecipitation with high throughput\
          \ sequencing is used to identify the DNA/RNA-associated proteins or protein\
          \ complexes.\nAs an immunoprecipitation it can be ChIP, RIP or another immunoprecipitation\
          \ process."
        meaning: EFO:0005032
        title: IP-seq

Which does not look the same as, for example, its rendering on EBI

I think this should be fixed in the tooling, as newlines are valid (if unusual) in textual elements. But we can merge this for now
