📜 Description

When I want to build for multi-variant projects, it gives me an error.
During troubleshooting, I realized that for all variants, only one version of the source map is uploaded.
By checking the sentry .gradle file, I realized that three variables are defined globally, but they are used inside the loop, and this makes these three variables retain the value of the last round of the loop. For this reason, the duplicate source map is uploaded.
For example, if I want to build for armeabi-v7a, x86, arm64-v8a and x86_64 variants, the source map for x86_64 will be uploaded four times because it is the last round of the loop.

💡 Motivation and Context

This pull request solves the problem of duplicate source map upload for all project variants.

💚 How did you test it?

Just create a multi-variant project and build it.
This is my build logs. As you can see, one version has been uploaded for all source map upload tasks:

Copy `debugId` from packager source map to Hermes source map...
Hermes combined source map already has `debugId`.

Sentry Source Maps upload will include the release name and dist.
