chore: remove lib dir from source-code & fix dev scripts

[YassinEldeeb]

Improvements

1. The lib directory which contains the compiled TS shouldn't be included in the actual source code of the project.
2. Add prepack script which runs on npm publish and before packing up the package tarball. And the prepack script just builds the package so that when npm publishes your package, It'll build the package first into a lib directory before publishing.
3. In schema.prisma mongoDB should be removed from the previewFeatures array because in the latest Prisma release it's considered now as GA.
4. Instead of excluding the tests folder in package.json from the package tarball, It's better to exclude it in tsconfig.json to skip compiling it which will also result in faster builds.
5. Add removeComments: true option in tsconfig.json to remove unnecessary comments from the build which will result in a smaller tarball size.
6. Rename start script to dev cause usually start means a script to run an app in a production environment but in this case, It's for development(not a big deal though 😅)
7. Remove the project directory arg from tsc -p . cause it defaults to the current directory.
8. Remove sudo from the local script cause developers on windows won't be able to use this script if it was prefixed with sudo (me included), If you have some issues on mac/linux when running this command without sudo that's usually a permissions issue in your home directory which can be fixed by reclaiming the ownership of the .npm directory
