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 for the new option
• 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

Test Fix

Changed the install test to use wp-cli/restful instead of wp-cli/test-package. The package name must match a real package in the package index, as the code validates against it.

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>
