This implements E2E tests for the following 3 items in the release testing grid:
7.4.1 Verify the symbol sidebar works in each of the following languages: Go (Test plan)7.4.2 Verify the symbol sidebar works in each of the following languages: TypeScript (Test plan)7.4.3 Verify the symbol sidebar works in each of the following languages: Python (Test plan)The added cost are the two new repos, appdash and sourcegraph-typescript. But those are necessary to have so we can test that the symbol bar works for Go, TypeScript and Python.
Regarding the tests themselves: I'm not sure how welcome "table-driven tests" such as these are in the TypeScript world, but since we want to test the same thing for multiple files in different languages I think this is the most readable and extendable version.
I also want to add a separate test in a separate PR that tests that clicking on a symbol navigates to its definition.
Note: the TypeScript test will fail if precise code intelligence is enabled, since Object and source are not in the list of symbols then.
