[FEATURE] Add support for Umami

[aozaki-kuro]

Describe the feature you want

mikecao/umami is a free self-hosted analytics as an alternative choice of Google Analytics and provides detailed info.

But unfortunately I don't know how to write Go 😞

I hope this could be added to the supported list.

Useful reference

The script added into

looks like this

<script async defer data-website-id="xxxxxxxx" src="https://example.com/umami.js"></script>

For the config.toml

[params.analytics.umami]
      id = "" # data-website-id
      domain = "" # replace example.com
