Add Volta tool to implement node version + toolchain manager

[lubska]

Feature idea

Volta is a JavaScript node version + toolchain manager. It lets you pin exact versions of Node.js, npm, yarn and pnpm per project, so everyone on the team uses the same versions automatically.
Volta installs tools once, caches them and switches versions instantly based on the project configuration, without manual setup. It works across platforms and integrates transparently into your shell and CI environment.

Advantages

• You don't need to manually run nvm use
• the correct version is picked up automatically when you enter a project
• it works consistently in the shell, IDE and CI environment
• it pins tool versions in package.json
