Fixed the code section inside Context::initialize method inside the getting_started.md

[SachinBahukhandi]

Earlier this change:

Context::initialize(
    apiKey: $_ENV['SHOPIFY_API_KEY'],
    apiSecretKey: $_ENV['SHOPIFY_API_SECRET'],
    scopes: $_ENV['SHOPIFY_APP_SCOPES'],
    hostName: $_ENV['SHOPIFY_APP_HOST_NAME'],
    sessionStorage: new FileSessionStorage('/tmp/php_sessions'),
    apiVersion: '2023-04',
    isEmbeddedApp: true,
    isPrivateApp: false,
);

Would be producing errors.

Thus, replaced it with:

Shopify\Context::initialize(
    'apiKey'=> $_ENV['SHOPIFY_API_KEY'],
    'apiSecretKey'=> $_ENV['SHOPIFY_API_SECRET'],
    'scopes'=> $_ENV['SHOPIFY_APP_SCOPES'],
    'hostName'=> $_ENV['SHOPIFY_APP_HOST_NAME'],
    'sessionStorage'=> new FileSessionStorage('/tmp/php_sessions'),
    'apiVersion'=> '2023-04',
    'isEmbeddedApp'=> true,
    'isPrivateApp'=> false,
);

@SachinBahukhandi the change is wrong. The documentation is using parameter naming instead an array for this. This PR should be closed
