JuliaFormatter `ignore` list is ignored

[mortenpi]

You can exclude some files from formatting with ignore = [...] in your .JuliaFormatter.toml. It seems like LanguageServer / VS Code's "Format on Save" will ignore this, and format the file anyway.

I suspect it's because LanguageServer calls JuliaFormatter.format_text, which doesn't know about the file identity of the code it's formatting?
