Replace "annotation inject" with "attribute Inject"

update to PHP 8.0 - replace annotation with attribute

Thanks, you're right that "annotation inject" is outdated — it's the #[Inject] attribute now. Incorporated in 1de725ea8, applied to both the Czech and English versions.

One note: I tested your exact markup [#[Inject] |…] in Texy and it doesn't render as a link — the ] inside #[Inject] prematurely closes the link, so the whole thing stays as literal text (backticks around it don't help either). So I linked the plain word Inject instead ("s atributem [Inject |…]" / "with the [Inject |…] attribute"), which renders correctly and still points to the Inject-attributes section. Closing since the branch can't be merged directly.
