Report a Problem page has no option to actually report the problem

[github-throwaway]

What

If you find a problem, and you want to report it, then there is no option to report it directly from the app.

Current text

Incomplete or incorrect information?
Category, labels, ingredients, allergens, nutritional information, photos etc.
If the information does not match the information on the packaging, you can complete or correct it. Thank you! Open Food Facts is a collaborative database, and every contribution is useful for all.
If you want to report vandalism, inappropriate content or erroneous data you can't fix yourself, report it to our moderators team.

Expected behavior

An option to actually report the problem. Either a form to fill out, a redirect to Slack, an email address, a link to GitHub, something that's not nothing.

Why

While it mentions reporting to moderators, it does not specify how to do so (e.g., via a button, email, or link). Users are left unsure about the next steps.

The same applies to the website.

@github-throwaway on the website you get an action:

The problem on the mobile app is that the action is not implemented yet !
Mobile App team wants to integrate the form directly in the app but it's a work in progress.

@teolemon should we eventually first implement it as a simple link and then later on as a native form ?

@alexgarel when I click the button on the website I got an error message. "Error .Invalid address" 😅

See openfoodfacts/openfoodfacts-server#11211

It's fixed for the website.

On the app, @Valimp is currently working on a native implementation #6315
