Allow https for Apprise

[schklom]

I suggest changing

node-toogoodtogo-watcher/lib/notifications/apprise-notifier.js

Line 25 in b28b013

return got.post(`http://${options.host}/notify/`, {

to

    return got.post(`${options.url}/notify/`, {

and

node-toogoodtogo-watcher/config.defaults.json

Line 28 in b28b013

"host": "apprise:8080",

to

      "url": "http://apprise:8080",

This would let users specify http or https without being overly complicated.

The intended use is to use Apprise as a sibling container.
Https would only be needed in a situation where Apprise is on a different host and behind a proxy setup that adds HTTPS.

I use Apprise for other services, not only this one.
For security, I try to separate containers and make connections via my reverse-proxy when possible, just in case.
