Feat: build the CI pipeline

[apoorvsadana]

This repo started from this boilerplate. So it already has some workflows in place. However, we haven't tested these workflows as of now. As a part of this feature, we need to complete the following tasks

1. Test the existing workflows if they are working correctly. Remove any unnecessary workflows with proper reasoning.
2. Ensure we are able to build correctly on all platforms
3. Sign the app and create a release on demand.
