[10.x] Fix parsing error in console when parameter description contains --

[rxrw]

Overview

This PR addresses an issue in the Laravel Console's signature parser where it would produce incorrect results if a parameter description contained --.

Problem

When defining a command's signature in Laravel Console, if a parameter description included --, it would lead to incorrect parsing of the command. This could cause unexpected behavior or even application errors depending on how the command was defined.

Example

When I generate a new command with signature:

protected $signature = 'check:api-routing {route_file : The file containing the main api routes generated by `php artisan route:list --json`}';

This is will produce following result:

Description:
  Check the differences between the api routing and the api routing file

Usage:
  check:api-routing [options]

Options:
      --json`
  -h, --help            Display help for the given command. When no command is given display help for the list command
  -q, --quiet           Do not output any message
  -V, --version         Display this application version
      --ansi|--no-ansi  Force (or disable --no-ansi) ANSI output
  -n, --no-interaction  Do not ask any interactive question
      --env[=ENV]       The environment the command should run under
  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Solution

I've made a targeted change to the regular expression used in the parameters method, specifically by adding a ^ to ensure that -- within a description does not interfere with the parsing process.

Here's a brief summary of the change:

• Updated the regular expression in the parameters method to include ^, ensuring proper handling of -- within parameter descriptions.

Impact

This minor yet crucial fix ensures that developers can include -- in parameter descriptions without any parsing issues. It improves the robustness of Laravel Console's command definition and parsing capabilities.
