Version is publicly exposed

[nevets963]

Within the /ping endpoint (https://github.com/getumbrel/umbrel-manager/blob/master/routes/ping.js#L5), the version of the component is publicly exposed which could aid an attacker to quickly identify known vulnerabilities within a given Umbrel version.

e.g.
0.2.17 shown in
https://testnet.getumbrel.com/manager-api/ping

As far as I can tell, the version isn't display anywhere in the dashboard, just set within the Vue state:
https://github.com/getumbrel/umbrel-dashboard/blob/686ae71962870b737cf84b0805b466be88b28c6d/src/store/modules/system.js#L37

Proposed solution: add JWT auth or remove version no. from response.

The exact same issue exists for the middleware too: https://github.com/getumbrel/umbrel-middleware/blob/master/routes/ping.js#L5
Happy to open an issue within the repo too
