feat(npm): Add support for installing npm package on Android

[szokeasaurusrex]

Android systems should be able to run the Linux binary. This change enables the Linux binary to be fetched when the npm package is installed on an Android system.

Fixes #2288

[szokeasaurusrex]

I tested this change by installing the commit via npm on an Android emulator. While the installation was successful, I received this warning message during installation:

[sentry-cli] Sentry CLI failed to locate the "@sentry/cli-linux-arm64" package after installation!

This can happen if you use an option to disable optional dependencies during installation, like "--no-optional", "--ignore-optional", or "--omit=optional". Sentry CLI uses the "optionalDependencies" package.json feature to install the correct binary for your platform and operating system. This post-install script will now try to work around this by manually downloading the Sentry CLI binary from the Sentry CDN. If this fails, you need to remove the "--no-optional", "--ignore-optional", and "--omit=optional" flags for Sentry CLI to work.

I believe this is occurring because the changes to the package.json for the optional dependencies are not reflected in npm yet, and npm does not know to look for them in this repo. So, in order to fully test this, I will make an alpha for the next release and try installing the alpha (from npm directly).
