[ANN] Stack 3.3.1

See https://haskellstack.org/ for installation and upgrade instructions.

Changes since v3.1.1:

Behavior changes:

Stack interprets consecutive line ends in the value of the user-message project-specific configuration option as a single blank line. Previously all line ends were interpreted as white space.
Stack no longer supports Docker versions before Docker 1.9.1 and, consequently, if a Docker container is not being run ‘detached’, its standard input channel will always be kept open. (Before Docker 1.9.1 the use of an interactive container could hang in certain circumstances.)
On Windows, Stack will always warn (message S-8432) if there is a space character in Stack’s ‘programs’ path, as GHC 9.4.1 and later do not work if there is a space in the path to the ghc executable. S-8432 now presents as a warning and not an error.
Stack respects the --no-run-tests and --no-run-benchmarks flags when determining build actions. Previously Stack respected the flags when executing the run test suites or run benchmarks actions for each targeted project package.

Other enhancements:

Consider GHC 9.10 to be a tested compiler and remove warnings.
Consider Cabal 3.12 to be a tested library and remove warnings.
Add flags --run-tests and --run-benchmarks (the existing defaults) to Stack’s build command, which take precedence over the existing no-run-tests and no-run-benchmarks configuration options, respectively.
In configuration files, the notify-if-no-run-tests and notify-if-no-run-benchmarks keys are introduced, to allow the exisitng notification to be muted if unwanted.

Bug fixes:

Stack’s in-app messages refer to https://haskellstack.org as currently structured. (Most URLs in older Stack versions are redirected.)
Stack’s upgrade command only treats the current running Stack executable as ‘stack’ if the executable file is named stack or, on Windows, stack.exe. Previously only how it was invoked was considered.
stack test --no-run-tests --dry-run no longer reports that Stack would test project packages with test suites and stack bench --no-run-benchmarks --dry-run no longer reports that Stack would benchmark project packages with benchmarks.
StackSetupShim compiles with Cabal >= 3.14.0.0.
