Phpstan just implemented "safer array key" support https://phpstan.org/blog/phpstan-2-2-unsealed-array-shapes-safer-array-keys#safer-array-keys

Part of this change is the use of a not-entirely-new type non-decimal-int-string. PhpDocumentor treats the use of that type as an error. Might you be able to support it? Treating it as if it were string is possibly sufficient.
