Add a schema change log page with recommended changes

[PonteIneptique]

We only add one schema.

We should provide a link to help people change their schema version (either with a tool but at least saying what changed).

Version 2021-10-15 -> Version 2022-04-15

• Added free-text field transcription-software. Recommended values:
  • eScriptorium + Kraken
  • Transkribus
  • OCR For All
• script is now a list of objects.
  • Basically, all script ISO values should become - iso: IsoValue such as - lat -> - iso: lat
  • Added the ability to specify a little more the script with a new free text field qualify
• Added an institutions object which reuses the pattern of authors, except that it forces name and does not support firstname
• orcid is now available for authors objects
• A new characters field is now available, it supports three sub-properties
  • A unicode normalization mode called mode, which can be None, NFD, NFKD, NFC, NFKC
  • A transliteration boolean to indicated whether script is transliterated (such as hieroglyphs): Default False
  • A members property which accepts a list of characters and represent all glyphs in the ground truth.

Do you think a link to this page should be in the navbar, or could it be in the footer?

Also, we need to do the same for the newest version: 2023-06-27

Changelog for 2023-06-27 is fairly simple:

Version 2022-04-15 -> Version 2023-06-27

• Image-Text-Pairs is now available for format objects.
• A new automatically-aligned boolean is now available to flag datasets resulting from automatic alignment. Default is False.
• Fixed type definition for transliteration and missing }.

But I don't know if it is useful to include the hot fix in the changelog 🤔

Keeping track here: Thibault suggested adding a "hotfix since release" subsection and I agree with it :)

Also, the hotfix on transliteration and the "}" needs to be applied to the previous schema as well.
