Can confirm, but note that the header is terminated by ..., is this really what you wanted?
I never heard of lua filter headers (do you have resources on that?), only yaml headers which are terminated by --- and are working correctly.
I assume Gitea tries to parse a yaml header, finds that it never terminates, and thus doesn't even start parsing or rendering markdown.

Hm, may not lua header, it is more or less yaml.

We use usage eisvogel.tex and the example from Usage shows this:

---
title: "The Document Title"
author: [Example Author, Another Author]
date: "2017-02-20"
keywords: [Markdown, Example]
...

Here is the actual document text...

Ah, may a bad example, which ... means there is more.

Nop also the basic-example use this syntax, see also the pandoc docs

It should have been fixed by Fix markdown frontmatter rendering #34102
