dhs.ttl broken -> has extra semi-colon

[jonathanvajda]

On line 172 of the dhs.ttl file, the subject 'dhs:transliterationStandard' has a semicolon before the predicate and object 'a rdf:Property'. This is broken.

dhs:transliterationStandard;
    a rdf:Property ;
    rdfs:label "Transliteration Standard"@en ;
    rdfs:isDefinedBy <http://github.com/usdhs/dcat-tool/> ;
    rdfs:range rdfs:Literal ;
    rdfs:comment "<p>The standard of converting  text  from one language to Roman characters.</p><p>Example:<ul class='no-bullets'><li>https://www.iso.org/ics/01.140.10/x/</li></ul></p>" ;
    .

I believe it should say

dhs:transliterationStandard
    a rdf:Property ;
    rdfs:label "Transliteration Standard"@en ;
    rdfs:isDefinedBy <http://github.com/usdhs/dcat-tool/> ;
    rdfs:range rdfs:Literal ;
    rdfs:comment "<p>The standard of converting  text  from one language to Roman characters.</p><p>Example:<ul class='no-bullets'><li>https://www.iso.org/ics/01.140.10/x/</li></ul></p>" ;
    .

I don't mind making a fix on a branch and then making a pull request, but I don't know your dev environment and whether you'd be receptive to this from an external contributor.
