Release 2.1.45

[github-actions]

Changes

2.1.45 - 2024-11-15

Changed

• Changed the name of the collections folder to validation.
• Remove all version suffixes from all source files, i.e., -v2.1.ttl becomes .ttl

Fixed

• Added skos:broader relations to a number of quantity kinds that had none. Note that it is ok for a
  quantity kind to have no broader quantity kind, but these were missing.
• Changed the erroneously used 'qudt:hasDimensionVector' property in vocab/types/VOCAB_QUDT_DATATYPES-v2.1.ttl
  file with with a new property qudt:dimensions that denotes the dimensions of a matrix.
• Introduced a maven based build process to automate the manual tasks required for merging PRs and making releases.
  This change does not affect the content of the ontologies.
• Replaced (hopefully) all occurrences of hr as a symbol for unit:HR with h.
• Add unit:NUM-PER-MilliL
