Can we reduce duplicated code and rewrite the current-functions as folllows?

  <xsl:function name="mcrclass:current-label-text" as="xs:string?">
    <xsl:param name="class" as="element()?" />
    <xsl:sequence select="mcrclass:label-text($CurrentLang, $class)" />
  </xsl:function>

  <xsl:function name="mcrclass:current-label" as="element()?">
    <xsl:param name="class" as="element()?" />
    <xsl:sequence select="mcrclass:label($CurrentLang, $class)" />
  </xsl:function>

We have https://github.com/MyCoRe-Org/mycore/pull/2144 for testing XSL functions. I would wait for this PR to be included and then write test to ensure unchanged behaviour.
