✨[RUM-5090] Collect resource protocol

[RomanGaignault]

Motivation

Adding the network protocol information (e.g., http/1.1, h2) to resource events will provide deeper insights into how resources are fetched by the browser.

Changes

Utilized performanceTiming.nextHopProtocol to obtain the protocol information for same-origin requests.
Note: nextHopProtocol is only available for same-origin resources and might be restricted by the Timing-Allow-Origin header for cross-origin resources.

Testing

• Local
• Staging
• Unit
• End to end

🔗 RealWorld

[BenoitZugmeyer]

You'll need to add that field in rum-events-format (around here), get it merged, run rum-events-format:sync in the SDK repo and update this PR

[BenoitZugmeyer]

💬 suggestion: ‏rename request_protocol to protocol, as it is not only the request protocol but also the response and everything around :)

[BenoitZugmeyer]

Put it in staging before merging the PR, to make sure it works as expected there.
