fix: support markup syntaxes

[jaredLunde]

Allows downstream packages like markup_fmt pass extensions for files that use markup/frontmatter syntaxes.

Closes #15

In general, users should be able to configure the plugin to run on these files since Biome can parse/format them on its own.

The code below formats js files, so won't this cause errors to surface for these file types? Maybe adding a test to this PR might help demonstrate the fix?

[jaredLunde]

This line below determines the JS syntax from the file path:

let Ok(syntax) = JsFileSource::try_from(file_path) else {

Which winds up here: https://github.com/biomejs/biome/blob/561b54c93625c9a83035562022af47237e6c00b2/crates/biome_js_syntax/src/file_source.rs#L300

I'm down to add a test though : )

[dsherret]

Oh, interesting. For adding a test it would just be adding a file like this one: https://github.com/dprint/dprint-plugin-biome/blob/main/tests/specs/Json.txt (but making the top line have a .svelte extension) then running cargo test

Also don't forget to add a thing for json and jsonc since it's fully supported in biome.

I tried writing a test and this doesn't work from what I can tell. I don't see any docs about biome being able to format these kind of files, but maybe it's there somewhere. It also seems to go into the biome_js_parser.
