ref(flags): mention spans/txn event support in JS integration docs (#14211)

Since JS
[9.31.0](https://github.com/getsentry/sentry-javascript/releases/tag/9.31.0)
our FF integrations capture flags on spans, which are sent in
[transaction
events](https://develop.sentry.dev/sdk/data-model/event-payloads/transaction/).
This PR updates the JS integration docs to mention this, and renames
"trace events" to "transaction events" in python
