.github: Ensure 7zip install for windows

Stack from ghstack:

• .github: Ensure 7zip install for windows #58924 .github: Ensure 7zip install for windows

Was observing behavior where 7zip was nowhere to be found after a build
was completed. Let's just have 7zip be installed within the workflow as
well just to be completely sure 7zip is there.

Just curious what’s 7zip used for? Power shell can do unzips natively and there’s also tar.exe on newer Windows 10s

We use it as part of build_pytorch.bat here:

pytorch/.jenkins/pytorch/win-test-helpers/build_pytorch.bat

Lines 115 to 124 in bf269fd

	python setup.py install --cmake && sccache --show-stats && (
	if "%BUILD_ENVIRONMENT%"=="" (
	echo NOTE: To run `import torch`, please make sure to activate the conda environment by running `call %CONDA_PARENT_DIR%\Miniconda3\Scripts\activate.bat %CONDA_PARENT_DIR%\Miniconda3` in Command Prompt before running Git Bash.
	) else (
	7z a %TMP_DIR_WIN%\%IMAGE_COMMIT_TAG%.7z %CONDA_PARENT_DIR%\Miniconda3\Lib\site-packages\torch %CONDA_PARENT_DIR%\Miniconda3\Lib\site-packages\caffe2 && copy /Y "%TMP_DIR_WIN%\%IMAGE_COMMIT_TAG%.7z" "%PYTORCH_FINAL_PACKAGE_DIR%\"
	:: export test times so that potential sharded tests that'll branch off this build will use consistent data
	python test/run_test.py --export-past-test-times %PYTORCH_FINAL_PACKAGE_DIR%/.pytorch-test-times
	)
	)

But perhaps that's not actually necessary and we should just defer to powershell's builtins
