The reason for this hook is not the validation itself, because that
is already done by `GadgetDefinitionContent->isValid` which is part
of the core Content interface, already enforced by ContentHandler.
Instead, the hook was here to provide the custom interface message
GadgetDefinitionValidator, because the core Content interface is
limited to boolean isValid(), which provides a very generic error
message.
However, nowadays ContentHandler exposes this mechanism directly
such that we can directly attach a custom message to it without
needing to wait for the stack to reach the EditPage and then override
it after the fact from a global hook.
Also:
* Simplify validation logic towards "is" checks with only an
expected description.
* Move schema.json file to top-level file.
It has been unused for as long as it has been in the repo, despite
appearing (due to its placement) to be used as part of the source.
It was added, I believe, with the intent to be used by the validator,
but it isn't. It also isn't validated or checked for correctness
by anything right now.
For now, keep it as informal schema in the top-level location for
easy discovery where perhaps others can find a use for it.
SD0001 mentions gadget developers may want to start using it for
Git-maintained gadgets to help with validation in their IDE, after
Gadgets 2.0 is launched.
Test Plan:
* Set `$wgGadgetsRepo = 'json+definition';`
* Create `MediaWiki:Gadgets/example.json`
* Attempt to save "x" in settings.namespaces item.
* Attempt to save "x.zip" in module.pages item.
* Fails with this patch, similar as on master.

For each item, either display human-readable and translated text,
or display a technical non-translatable identifier as `<code>`,
with optional localised text in the title attribute.
* Re-format "rights" as a sentence instead of a bullet list. It was
the only one using a bullet list, which made it feel a bit long.
* Re-format "actions" as `<code>` since they are not localised.
* Re-format "contentModels" as `<code>`, and add the localised display
name in a title attribute, same as we do with "rights" already.
ContentHandler::getLocalizedName() is also used already on
Special:ChangeContentModel.
* Fix "contentModels" to set `needLineBreakAfter = true`, otherwise
if a gadget also sets "supportsUrlLoad", then that sentence is
appended to the previous line.
Update phrasing and sorting to be consistent everywhere, and adopt
native PHP types where possible.
In most cases, I made things alphabetical, with the exception of
Special:Gadgets user interface output, and Gadget class methods,
which both follow the order of most recently added feature last
(rights, skins, actions, namespaces, contentmodels, categories).
Highlights:
* Fix namespace IDs type. These can be strings when they are parsed
from the gadget definition text, not always integers.
* Add explicit default for 'category'. In theory not needed because
MediaWikiGadgetsDefinitionRepo has a `$section = '';` default, and
MediaWikiGadgetsJsonRepo uses GadgetDefinitionContentHandler where
`category: ''` is part of both the initial page content, as well
as merged via getDefaultMetadata.
This default benefits simpler test cases, and static analysis,
since the Gadget class constructor does not (yet) require it.
Without this, getCategory() could TypeError due to returning null.

Adds a "categories" option to the gadget definition, which takes a
list of category names. Enabled gadgets will only load when the
viewed page is in one of the required categories.
