Bug: Lexer.matchAtrulePrelude Cannot read properties of null (reading 'match')

[carlosjeurissen]

When having at-rules like @font-face, I'm getting the following error since v2.2.0:

TypeError: Cannot read properties of null (reading 'match')
    at matchSyntax (/node_modules/.pnpm/css-tree@2.2.0/node_modules/css-tree/cjs/lexer/Lexer.cjs:82:51)
    at Lexer.matchAtrulePrelude (/node_modules/.pnpm/css-tree@2.2.0/node_modules/css-tree/cjs/lexer/Lexer.cjs:289:16)

Fixed in v2.2.1
