docs: fix broken anchors and stale Doctrine annotation references (#799)

Doctrine annotation support was dropped in #677, and the relevant
section headings were subsequently renamed from "annotation"/"annotations"
to "attribute"/"attributes". A handful of in-repo links and wording
were missed in that rename:

- annotations-reference.md #[Type] section: `#input-annotation` /
  `#factory-annotation` → `#input` / `#factory` (sections are now
  `## #[Input]` and `## #[Factory]`).
- authentication-authorization.mdx + fine-grained-security.mdx:
  `#logged-and-right-annotations` → `#logged-and-right-attributes`
  (section is `## #[Logged]` and `#[Right]` attributes`).
- queries.mdx "About attributes": the Doctrine example was shown as
  `#[Query]`, which is the new-style syntax. Corrected to `@Query` and
  rephrased the line so the old-vs-new distinction actually reads.
- annotations-reference.md intro: reworded to reflect that only the
  PHP 8 attribute format exists now; kept the link to the migration
  guide since existing users still need it.
- annotations-reference.md #[Assertion]: Type column said `annotation`
  while the description said `attributes` — aligned to `attribute`.

Intentionally left alone: CHANGELOG.md (historical), migrating.md
(historical migration guide), doctrine-annotations-attributes.mdx
(migration guide, still useful), and the `annotations` parameter on
#[SourceField] / #[MagicField] (actual PHP parameter name in the
source). PHP namespace references (TheCodingMachine\GraphQLite\
Annotations\*) are real symbol names and not stale.
