Bring in inspector_protocol as a direct dependency

Currently, node.js depends on [inspector_protocol](https://www.google.com/url?q=https://chromium.googlesource.com/deps/inspector_protocol/) indirectly through the dependency on v8.

This is a dependency violation that will make it hard to roll V8 into
Node if V8 gets a newer inspector protocol version with incompatible
API. In fact, this surfaced on one of our bots when we tried to roll new
inspector_protocol into V8: [upstream patch](https://chromium-review.googlesource.com/c/v8/v8/+/1149321).

This patch adds inspector protocol and its required dependencies to node
deps:
- jinja2
- markupsafe
