Add --no-interaction flag to prevent Git/SSH prompts in package commands

[Copilot]

Add --no-interaction flag to package commands to prevent interactive prompts

• Add --no-interaction flag to wp package install command
• Add --no-interaction flag to wp package update command
• Add --no-interaction flag to wp package uninstall command
• Set GIT_TERMINAL_PROMPT=0 environment variable when flag is used
• Set GIT_SSH_COMMAND=ssh -o BatchMode=yes when flag is used
• Update command documentation with new option
• Add tests that verify Git/SSH operations don't prompt interactively
• Document method parameters and putenv() usage
• Change flag to interaction with default true (WP-CLI converts --no-interaction to --interaction=false)
• Keep --no-interaction usage in tests
• Fix test to use real package name from package index

Implementation Details

The flag is implemented as interaction with a default value of true:

• Code checks for interaction flag with default true
• When interaction is false, non-interactive mode is enabled
• Tests use --no-interaction which WP-CLI automatically converts to --interaction=false
• Documentation uses [--interaction] syntax

Tests

The tests verify actual non-interactive behavior with Git/SSH operations:

• Install test: Attempts to install from a private/non-existent Git repository and verifies it fails fast with error messages instead of hanging for credentials
• Update test: Installs a real package then updates with --no-interaction to ensure it completes without hanging on credential prompts
• Uninstall test: Uninstalls a package with --no-interaction to ensure the operation completes without prompting

With --no-interaction, Git operations fail immediately with error messages instead of waiting for user input. Without the putenv() calls, these operations would hang indefinitely waiting for credentials in interactive mode.

This section details on the original issue you should resolve

<issue_title>Add option to be non-interactive.</issue_title>
<issue_description>See #60 (review)

Composer supports being run non-interactively so it could be useful to have an option to set this.

In particular it would avoid getting prompted for one's ssh password as can happen depending on one's authorization settings, which is problematic for scripts.</issue_description>
