Some UMLS CUI (P2892) concerns

@Sebotic, I9606, Putmantime, Andrawaag, Emitraka, Pigsonthewing: and https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Medicine, https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Molecular_biology

• It says "equivalent property: http://identifiers.org/umls/". But that's not a property! It's a namespace for the identifier, and even that is slightly misspelt. If you go to that URL, you get "Resolution request 'umls/' is NOT A NAMESPACE; For namespace 'umls', provided local ID DOES NOT MATCH local IDs definition pattern...
• It says "format as a regular expression: C\w\d{6}". But https://registry.identifiers.org/registry/umls and the error above both say the regex is '^C\d+$'. Is there any evidence that the second char can be alphabetical and not a digit? I propose to change the regex to C[1-9]\d{6}

Note: I've added two "third party formatters":

• https://identifiers.org/umls:$1
• http://linkedlifedata.com/resource/umls/id/$1
