Add missing link for Apple Developer ID in macOS packaging guide

[JcabreraC]

Description

The current macOS packaging guide (https://documentation.wazuh.com/current/development/packaging/generate-osx-package.html) instructs users to obtain an "Apple Developer ID" and refers to a link for obtaining this ID. However, the hyperlink associated with "this link" is missing, leading to potential confusion for users trying to follow the guide.

Expected Changes

• Documentation Update: Add the missing hyperlink to the section discussing the Apple Developer ID.
• Verification: Ensure that the link directs users to the appropriate Apple page where they can apply for the Developer ID and enroll in the Apple Developer Program.
• Clarification: Provide additional guidance on the process of enrolling in the Apple Developer Program, including any prerequisites such as two-factor authentication (2FA).

By resolving this issue, we aim to provide clearer guidance to users, ensuring they can seamlessly complete the macOS packaging process without external support queries.
