textproc/ruby-nori: update to 2.7.0

2.7.0 (2024-02-13)

* Added support for ruby 3.1, 3.2, 3.3. Dropped support for ruby 2.7 and
  below.
* Feature: Nori::Parser has a new option, :scrub_xml, which defaults to
  true, for scrubbing invalid characters (#72).  This should allow documents
  containing invalid characters to still be parsed.
* Fix: REXML parser changes &lt; inside CDATA to < (#94)
* Change: Object#blank? is no longer patched in.
