📊 Analytics: Support Umami Analytics

[ToddE]

Support for Umami Analytics (https://umami.is)

Umami analytics can be used with Umami Cloud or by self hosting umami.
Hugo configuration supports default umami cloud or self-hosted url through setting params.toml variable

Update to head.html

<!-- Umami Analytics -->
{{ with site.Params.umami }}
{{ if .enable }}
{{ with .id }}
<script defer src="{{ site.Params.umami.url | default "https://cloud.umami.is/script.js" }}" data-website-id="{{ . }}"></script>  <!-- enables user to change script location if self-hosting -->
{{ end }}
{{ end }}
{{ end }}

Setting umami variables in params.toml

# umami analytics: see https://umami.is/
[umami]
enable = false # set to 'true' to enable umami
# url = "https://cloud.umami.is/script.js" # allows user to select a self-hosted location instead of umami cloud
id = "" # umami website ID
