New Features

Node 22 is now supported
FetchError now implements WithProblemDetails: it has a .problemDetails getter providing
additional information about the HTTP error response, either provided by the server if it
supports RFC9457, or falling back to defaults.

Patch changes

Fixed #2339: Unnamed policies are now returned by getResourcePolicyAll if an optional argument
{ acceptBlankNodes: true } is specified. This additional argument makes this a non-breaking change,
as the current type signature isn't changed.
getThing now supports Blank Node identifiers in addition to IRIs and skolems to refer to a subject.
getThingAll(dataset, { allowacceptBlankNodes: true }) now returns all Blank Nodes
subjects in the Dataset, in particular including those part of a single chain of
predicates. For instance, given the following dataset:
```
@prefix ex: <https://example.org/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .

ex:camille
  foaf:knows [
    foaf:name "Dominique"@en ;
  ] .
;
```
getThingAll(dataset, { allowacceptBlankNodes: true }) would have previously returned
a single element for the Named Node (ex:camille), it will now also include a second
element for the Blank Node. Blank Node identifiers are by definition unstable and shouldn't
be relied upon beyond local resolution.
