improper language codes returned in some data sets

[lwhiteley]

eg.
request: SchoolHolidays?countryIsoCode=CH&validFrom=2026-03-10&validTo=2027-03-09

comment entry with "language": " o", seems out of place

"comment": [
  {
    "language": "DE",
    "text": "deutschsprachig"
  },

  {
    "language": " o",
    "text": "ne Tourismusgemeinden"
  },

  {
    "language": "FR",
    "text": "germanophone"
  },

  {
    "language": "EN",
    "text": "German-speaking"
  }
]

Notes (extra context):

• zod was used on the receiving end to strongly parse the data and found these discrepancies
• had to remove the strong schema for the iso code for now

DE deutschsprachig, ohne Tourismusgemeinden

either the comma is not escaped properly or it shouldnt be there.

what is intended to be said in german there?
