web: keep telemetry enabled in the dev env

Created by: valerybugakov

Context

Re-enable telemetry events until the underlying problem is solved: thread about the issue. A couple of pull requests that disable telemetry events in the development environment:

1. Initial https://github.com/sourcegraph/sourcegraph/pull/33010
2. Follow-up https://github.com/sourcegraph/sourcegraph/pull/33994

Created an issue to undress the underlying problem: https://github.com/sourcegraph/sourcegraph/issues/34768

Question

How disturbing is the fact that we log telemetry events from the development environment? If it's a critical issue then we can consider prioritizing the fix for the underlying problem and this PR can be closed. (cc @ebrodymoore as I saw your review on @erzhtor initial PR)
