chore: use rangutopia for building wallets

[yeager-eren]

Summary

Replace build/command.js with rangutopia scripts.

Fixes RF-2438

How did you test this change?

We should test in two phase, the first one using local linking (before rangutopia is available on NPM) and second when it's published.

Phase 1: local (NO NEED THIS ONE ANYMORE)

First run:

yarn

We only want to test two packages at this phase, the output of script and rangutopia should be same:

cd wallets/core/ 
yarn clean
yarn build2
mv dist dist2
yarn build
diff -qr dist dist2

do same for wallets/provider-ledger.
Note: not sure why hashes are different but content seems to be same. you can check them using this tool.

You can also run from root:

yarn workspace @rango-dev/wallets-core run build

Phase 2: npm

we've published the initial version, https://www.npmjs.com/package/rangutopia?activeTab=readme

just yarn and start to see the build output
