Add Plausible. Closes #80

[juliangruber]

Closes #80.

• Set up Plausible project for app.station.filecoin.io
• Invite @patrickwoodhead and @bajtos as admins
• Integrate Plausible script

@bajtos documented these events to be captured, which I think are already covered by default:

Modify Station UI to report the following events

• a user starts the app (the onboarding flow)

This is a pageview on / or /onboarding or whatever we want to call the route, as long as it isn't the same URL as the dashboard. In the current version, / is onboarding and /saturn is the dashboard.

• the user closes the app at the screen “Enter FIL”

Plausible lists "exit pages", as long as the "Enter FIL" screen has its own URL this will be taken care of already.

LGTM 👍🏻

This is a pageview on / or /onboarding or whatever we want to call the route, as long as it isn't the same URL as the dashboard. In the current version, / is onboarding and /saturn is the dashboard.

It would be great to have /onboarding instead of / for onboarding screens. I think that's out of scope of this PR. We can handle this in #75 or later. /cc @jopedroliveira

sounds great, we also briefly discussed this in Slack this morning (https://filecoinproject.slack.com/archives/C03N9ENJL77/p1663192253013309)
