Feature Request: Name exports after the data they contain, not export.csv for example

[HaynesPostHog]

Feature request

Is your feature request related to a problem?

Using a generic name like "export.csv" makes it difficult to manage when downloading multiple files, as they all end up with the same name.

Describe the solution you'd like

Dynamically name the CSV file based on the cohort name (e.g., "power-users-cohort.csv" or "trial-users-cohort.csv"). A datestamp of the export time would also be a nice addition.

Hi @benHPostHog I would like to work on this issue, if its not fixed already

We're including cohort name in exports as of https://github.com/PostHog/posthog/pull/32464 - there's already code that would allow this to be extended for other export types that don't already do this
