Review old "needs backport" PRs

[The-Compiler]

Looks like we have 35 old PRs with a "needs backport" label:

https://github.com/pytest-dev/pytest/pulls?q=is%3Apr+is%3Aclosed+label%3A%22needs+backport%22

Can we remove that, so we can use the label as a kind of "todo list" in the future still? What about the "backported" label, is that needed really?

Sure, we probably just forgot to remove them after backporting.

What about the "backported" label, is that needed really?

It serves as a marker that a PR was actually backported; just removing the needs backport label leaves the situation ambiguous, because we don't know if a PR has been backported or we forgot to do it entirely.
