Bring back visitors tracking

[m-aciek]

Use Plausible's top-stats endpoint, along with backoff configuration for retrying.

For reference, that's a sample full response content of the endpoint:

{
    "meta": {
        "imports_included": false,
        "imports_skip_reason": "no_imported_data"
    },
    "from": "2024-06-03",
    "interval": "month",
    "to": "2025-02-20",
    "sample_percent": 100,
    "top_stats": [
        {
            "name": "Unique visitors",
            "value": 45416,
            "graph_metric": "visitors"
        },
        {
            "name": "Total visits",
            "value": 50711,
            "graph_metric": "visits"
        },
        {
            "name": "Total pageviews",
            "value": 85781,
            "graph_metric": "pageviews"
        },
        {
            "name": "Bounce rate",
            "value": 72,
            "graph_metric": "bounce_rate"
        },
        {
            "name": "Time on page",
            "value": 124,
            "graph_metric": "time_on_page"
        }
    ],
    "comparing_from": null,
    "comparing_to": null,
    "includes_imported": false,
    "with_imported_switch": {
        "visible": false,
        "togglable": false,
        "tooltip_msg": null
    }
}

How much do we need visitor numbers? I'd prefer to sort this out properly with Plausible (we're following up via internal channels). But even so, translation progress isn't clearly causally linked to demand for translated versions, and readership of translated versions might have a closer relationship to latent demand rather than progress (capturing 100% of a market 1% the size).

Putting the PR to draft, to let sort it out properly first 👍

Visitor number reflects the impact of the translation on people. I agree that it's related to (induced by?) the completion. In my opinion it's an interesting metric to track. It can be motivating for the translations contributors.

How about we link to the dashboard (with the desired filter) instead?

Closing this, as issue has been closed, and discussion is necessary.
