chore: Update RUM models to fix webview integration tests

[ncreated]

What and why?

🧰 Fixes the impact of recent update in rum-events-format: DataDog/rum-events-format#177. The PR to Browser RUM schema has changed optionality of the RUMConnectivity.interfaces field (non-optional → optional) breaking decoding of browser events in our WebView integration tests:

failed - keyNotFound(CodingKeys(stringValue: "interfaces", intValue: nil), Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "connectivity", intValue: nil)], debugDescription: "No value associated with key CodingKeys(stringValue: \"interfaces\", intValue: nil) (\"interfaces\").", underlyingError: nil)):

How?

I updated RUM models to the new commit in rum-events-format, so we use recent schema for decoding Browser events.

This comes along with 2 changes to rum-models-generator after DataDog/rum-events-format#177:

• That PR added an enum with case names starting with digits (Connectivity → Effective Type: "2G", "3G", "4G"). Because enum cases in Swift cannot start with digit, the generator now sanitizes them by adding a prefix (the name of the enumeration).
• That PR also changed interfaces: [Interfaces] to be optional (interfaces: [Interfaces]?). Because one of the cases in Interfaces enum is named "none", this caused compiler ambiguity with Optional<Interfaces>.none. To avoid this, in such situation the generator also uses the prefix (<enumName>None).

🎁 As a bonus, I added an option to the make command so we can now generate RUM and SR models for a certain commit of the rum-events-format repo, e.g.:

make rum-models-generate git_ref=389581be98dcf8efbfcfe7bffaa32d53f960fb6f

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference
• Add CHANGELOG entry for user facing changes

Custom CI job configuration (optional)

• Run unit tests for Core, RUM, Trace, Logs, CR and WVT
• Run unit tests for Session Replay
• Run integration tests
• Run smoke tests
• Run tests for tools/
