lucene-facet-4.10.1 version not changed in 'DirectoryTaxonomyWriter'

[Jigar Shah]

Hello Lucene commiters,

I saw one inconcistent version usage lucene-facet-4.10.1.jar.

lucene-facet-4.10.1.jar uses deprecated 'Version.LUCENE_4_10_0" in class
'DirectoryTaxonomyWriter' 'createIndexWriterConfig'

Ignore it if it is deliberate.

Thanks,
