Syntax highlighting for Liquid templates

[darthmall]

I've followed the instructions in issue #11207 for adding support for Liquid templates to helix, but I don't get syntax highlighting. If anyone can help me get this working, or help me figure out how to debug this, I'd be grateful.

languages.toml

[language-server.shopify-theme-check]
command = "shopify"
args = ["theme", "language-server"]

[[language]]
name = "liquid"
language-id = "liquid"
scope = "source.liquid"
injection-regex = "^liquid$"
file-types = ["liquid"]
roots = [".git"]
language-servers = ["shopify-theme-check", "emmet-lsp"]
block-comment-tokens = { start = "{% comment %}", end = "{% endcomment %}" }

[[grammar]]
name = "liquid"
source = { git = "https://github.com/hankthetank27/tree-sitter-liquid", rev = "e45dbac8c5fa95b1f0e00e7e0c04bc8855823391"}

It looks like it should be working. Is there somewhere else I can check for errors?
