Summary of changes

Pass --no-input to Pip.

Fixes #219

This is a breaking change for keyring users. But was it ever properly supported anyway? As someone who needs the artifacts-keyring package to authenticate with our private repo I'm going with the answer being no, you will have to apply hacks if this is important to you. Failing fast is better then hanging forever because the user can't see the prompt asking for a username and password.

pypa/pip#11698 which is released in Pip 23.1 added a section to the documentation how Pipx users who rely on the keyring library can set things up so keyring will be used again: https://pip.pypa.io/en/stable/topics/authentication/#using-keyring-as-a-command-line-application.

Test plan

It should not have any impact when keyring is not required to authenticate with the repository.

Tested by running the test suite.

pipx run --index https://pypi.org/simple/ cowsay no input

Suggested change

	cmd = (
	["--no-input", "install", "--no-dependencies"]
	+ pip_args
	+ [package_or_url]
	)
	cmd = [
	"--no-input",
	"install",
	"--no-dependencies",
	*pip_args,
	package_or_url,
	]

We should probably use this chance to change other command-building code as well.

I left some in the form of cmd = [<snip>] + cmd alone instead of changing it to cmd = [<snip>, *cmd].
