docs(ledger-browser): add links to documentation

[outSH]

Is your feature request related to a problem? Please describe.

Ledger browser apps have an option to provide links to relevant documentation pages. Since documentation for ledger-browser has been commited, we can link it in app definitions.

Describe the solution you'd like

Edit eth-browser and fabric-browser app configuration (e.g. https://github.com/hyperledger/cacti/blob/main/packages/cacti-ledger-browser/src/main/typescript/apps/eth/index.tsx) and set their appDocumentationURL and appSetupGuideURL to point to web docs (e.g. https://hyperledger.github.io/cacti/cactus/ledger-browser/plugin-apps/ethereum-browser/). Setup should point to Setup chapter.

See if links are displayed correctly when using the app (top-right corner) and creating and app (Setup guide link).

Additional context

For more info on app config see ledger-browser development guide (https://hyperledger.github.io/cacti/cactus/ledger-browser/developer-guide/overview/)
