Download Link in documentation point to platform homepages

[O-sama12]

The download linked listed in the documentation currently points to the platform homepages instead of the application's specific pages.

Examples:

• GitHub ----> https://github.com
• Gitlab ----> https://gitlab.com
• F-Droid ----> https://f-droid.org
• Play Store -----> https://play.google.com
• Coolapk ----> https://coolapk.com

As a result, users are redirected to the platform homepages and must manually search for the application.

Expected behavior:
The links should point directly to the project's repository, release page, or application listing on each platform
