Support html in homeSubtitle in index.html

[fnobilia]

It would be cool having the possibility to handle HTML href in homeSubtitle. This way you can add stuff <MY POSITION> at <COMPANY HREF>.

My take would be adding an extra parameter called homeSubtitleWithHtml and then in index.html replace

{{- with .Site.Params.homeSubtitle }}
  <p>{{.}}</p>
{{- end }}

with

{{ if .Site.Params.homeSubtitleWithHtml }}
  {{- with .Site.Params.homeSubtitleWithHtml }}
    {{. | safeHTML }}
  {{- end }}
{{else}}
  {{- with .Site.Params.homeSubtitle }}
    <p>{{.}}</p>
  {{- end }}
{{ end }}

Not sure if that's the best way to achieve this. If you like the approach, I can open a PR this way you can comment.

BTW, amazing job! It's really useful! Thx a lot! 👏

@fnobilia I like it! I would submit a PR and make sure to update docs with the new param. 🤞 maintainer likes what they see. :D
