ci: fix and refactor enterprise release pipeline

[a7medev]

Description of the change

1. Change the find and replace logic in CI code to use a JavaScript script instead of sed to avoid issues with escaping special characters.
2. Refactor NN and Injazat's release to use the same job but with different parameters instead of different jobs.
3. Fix NN, Injazat, and Dream11's packages sourcemaps upload script, the ios/sourcemaps.sh and android/sourcemaps.gradle scripts referred to instabug-reactnative to invoke the upload CLI in the past so we fixed the release pipelines to replace all occurrences of instabug-reactnative with the new package name in these files as well.
4. Replace the API URL used to upload SO files in the CLI to refer to the API URL of the customer instead of the default Instabug API.

I tested the new release_custom_package and release_d11 CI jobs on the test-only @instabug/react-native-private to make sure things are working fine.
