Umami Support #2288
Description
Is your feature request related to a problem? Please describe.
I hope to use Umami to track my webpage usage, but I can't find a good way to inject an HTML JavaScript Tag in the Header.
Describe the solution you'd like
Add a head item for Formatter, supporting insertion of HTML JavaScript Tag.
Describe alternatives you've considered
I considered manually modifying the packaged Index.html, but that's too inelegant, and I have many Slidev presentations, so doing it that way would be too much trouble.
