Rename packages to already existing package in @warungpintar scope

[resir014]

So it turns out that we've previously published the same configs that we have here. Let's publish these new packages over the existing ones, marking the changes as breaking (minor version bump since we're still at v0.x).

Suggestions

• warung-config-eslint -> @warungpintar/eslint-config
• warung-config-prettier -> @warungpintar/prettier-config
• warung-config-tsconfig -> @warungpintar/typescript-config

Legacy package deprecations

• @warungpintar/eslint-config-base + @warungpintar/eslint-config-typescript -> @warungpintar/eslint-config
  (unified config for both JS + TS)

Blockers

Access to npm org still needed.
