MKVToolNix 93.0 “Goblu”

# Version 93.0 "Goblu" 2025-06-14

## New features and enhancements

* all: updated the various lists that go into IETF/BCP 47 language tags: ISO
  639 languages; ISO 3166 countries; ISO 15924 regions; IANA subtag
  registries.
* translations: added a Hungarian translation of the programs & man pages by
  Viktor György, John Fowler & Attila Zsigus (see `AUTHORS`).
* mkvextract: tags extraction: added an option `--no-track-tags` (short: `-T`)
  for not extracting tags associated with tracks.
* MKVToolNix GUI: multiplexer: the default regular expression for deriving the
  "forced display" track flag from file names for subtitles was extended to
  also match on the term `signs`. Implements #6094.
* MKVToolNix GUI: preferences: the revert buttons for the various "default
  regex for…" will only be enabled when the current text differs from the
  default, in other words: when reverting would actually change the
  text. Part of the implementation of #6099.
* MKVToolNix GUI: preferences: the GUI will now auto-upgrade the "default
  regex for…" to their respective current default values if they're still set
  to one of the previous default values. Part of the implementation of #6099.
