Minor Changes
6803e99: Adopt the hand-written
liquid-html-parserfor performanceReplace the parser-combinator-based Liquid/HTML parser with a hand-written

resilient parsing (it recovers from malformed input instead of bailing), and is
adapted to the theme-tools source model.
theme-language-server-common,theme-check-common,prettier-plugin-liquid, andtheme-graphare updated toconsume the new parser.
