fix: exclude android unit tests from being published to npm

[kirillzyusko]

📜 Description

Exclude tests folder on android on npm.

💡 Motivation and Context

The original size of this folder is about ~7kb and may be bigger in the future:

But in a reality those files are not used when devs add the package to their projects. So for sake of the optimization let's exclude those files from publishing to npm 🤞

📢 Changelog

JS

• exclude android/src/test path;

🤔 How Has This Been Tested?

There is no way to test that everything will work, but size-diff shows that folder was excluded (because size has been decreased).

📸 Screenshots (if appropriate):

📝 Checklist

• CI successfully passed
• I added new mocks and corresponding unit-tests if library API was changed
