Add Framework specific versions of Node SDK installation method guides

[Lms24]

Core or SDK?

Platform/SDK

Which part? Which one?

@sentry/node and friends

Description

Our current (alternative) installation method guides for the Node SDK (example) are generic to all node-based platforms in the docs. This means that they miss certain framework-specific snippets, like adding an error handler to the user app.

Suggested Solution

We should create tailored versions of these guides for each framework.

### Frameworks
