Regex is too limiting

[felixfbecker]

Currently lines matching this pattern are matched:

/start_?span\(['"]([^'"]+)['"]/gi

This is way too limiting. For example, in our own repo sourcegraph/sourcegraph, that only matches 2 (two) calls:

In sourcegraph-typescript, it only matches some helper functions with dynamic operation names:

Most calls are with StartSpanWithContext, or tracePromise/traceObservable in sourcegraph-typescript.

We need to find a solution for this to make the extension actually useful.
