existingIssuesUrl should be configurable

[Half-Shot]

Your use case

What would you like to do?

https://github.com/matrix-org/matrix-react-sdk/blob/d835721ae1dd005b7c0ba5b4b2448f5396128e1a/src/components/views/dialogs/FeedbackDialog.tsx is currently hardcoded to take a issue url that points to this repo with preconfigured labels. We'd like to instead allow this to be configurable.

Why would you like to do it?

Certain instances like to apply additional tags like Z-FOSDEM which is useful when running a conference.

How would you like to achieve it?

Override option in config.json

Have you considered any alternatives?

We currently just hack together a branch every year, but it kinda sucks.

Thank you ! This was a change we needed as well. 👏
