Enhance Temporal Connection Configuration with SSL Support and Flexibility

[butschster]

This PR introduces the ability to configure multiple connections to Temporal servers, including SSL-enabled connections. It aims to provide greater flexibility and security in connection setup, improving upon the previous single-address configuration approach.

Key Changes

• Added support for defining multiple connection options, including SSL configurations, in a structured array format.
• Introduced SslConnection for SSL-specific settings.
• Enabled dynamic connection selection based on environment variables.

Previous Configuration:

<?php

return [
   'address' => env('TEMPORAL_ADDRESS', '127.0.0.1:7233'),
];

**New Configuration:

<?php

use Spiral\TemporalBridge\Connection\DsnConnection;
use Spiral\TemporalBridge\Connection\SslConnection;

return [
    'connection' => env('TEMPORAL_CONNECTION', 'default'),
    'connections' => [
        'default' => new DsnConnection(
            address: env('TEMPORAL_ADDRESS', 'localhost:7233'),
        ),
        'ssl' => new SslConnection(
            address: env('TEMPORAL_ADDRESS', 'localhost:7233'),
            crt: '/path/to/crt',
            clientKey: '/path/to/clientKey',
            clientPem: '/path/to/clientPem',
            overrideServerName: 'overrideServerName',
        ),
    ],
];

Motivation

Enhancing security and deployment flexibility by supporting SSL connections and allowing configurations to adapt dynamically to different environments.

Testing & Backward Compatibility

• Conducted tests confirm both the new SSL configurations and the default non-SSL connections work as expected.
• The update maintains backward compatibility with the existing single-address configuration approach.
