Fixed changelog entry for haddock-package command

Make validate.sh show the output of cabal-plan

Closes #8440

* [ mergify ] fix condition of 'merge delay passed' label

Add the same conditions that we apply for the last stage of PR: 2 approvers and merge-me label. Otherwise, we get a lot of old PRs as well as some current ones getting the label prematurely.

* Remove warning on option -threaded when building libraries

Fixes #8431. Accompanied by option -flink-rts, option -threaded defines
the flavour of the ghc RTS library the built library will be linked
against. Note that bare ghc does not warn when option -threaded is used
for building a library either.

* Cabal no longer warns on -threaded option when building libraries

Note that this commit modifies regression check for issue #774.

* A small changelog was added

The proper way to print stuff is not a naive `putStrLn`, but using one
of the methods from Distribution.Simple.Utils, like `notice verbosity`.

Also allow latest aeson, network-wait, optparse-applicative in cabal-testsuite.

- add cabal-install-solver to the list of main packages in the repo

- turn ways to install cabal-install into a list instead of a sequence of headers

- add GHCup as the preferred option for getting cabal

- add a reference to CONTRIBUTING.md

Add some debugging to CmdRun/Terminate test

We've seen some instability in the test, compare

  https://github.com/haskell/cabal/issues/8416

This adds timestamped output to make it easier to
see what goes wrong in case the test fails again.

This makes the `finally` apply to the last `do` block as intended.
No real effect on the test, though.

Bump cabal-bootstrap-gen to GHC 9.2.4 ecosystem.

Also polish README a bit.

ci: use ubuntu-latest instead of ubuntu-18.04

Fix optional test-suite/benchmark type docs

[ docs ] fix typo in cabal update’s help

Exclude CI job 8.10.7 on Windows that corrupts all CI

This reverts commit cd7a9128.

It's not needed any more, probably, because another workaround
fixes CI differently, probably. As long as it's deterministic enough...
