Fix: TypeScript Build Bugs

[ShivanshVij]

This PR fixes various TypeScript build bugs, as well as a few Rust and Golang build bugs:

1. Environment Variables set during the scale function build command now get passed properly to the downstream commands
2. The build system now allows for wasi and wasm targets depending on the user's choice
3. The Rust build step now properly verifies the build target with Cargo
4. Using init function for Rust plugins now properly builds and does not cause builds to break
5. The TypeScript manifest generator for builds and signatures now returns a pretty-printed package.json
6. The signature builder now returns the tar.gz format for TypeScript signatures as well as the raw files
7. The storage manager now properly generates TypeScript signatures for both the guest and the host
8. Dependencies have been updated
