Broken highlighting when using sigils in arguments

def test(~s'"' <> value) do
  {:ok, value}
end

The lexer is treating '"' as a heredoc promoter. I need to figure out why it's mixing the two quote types in the regex.

🤦‍♂️

SIGIL_HEREDOC_PROMOTER = ({SIGIL_DOUBLE_QUOTES_PROMOTER}|>
{SIGIL_SINGLE_QUOTES_PROMOTER}){3}
SIGIL_HEREDOC_TERMINATOR = ({SIGIL_DOUBLE_QUOTES_TERMINATOR}|>
{SIGIL_SINGLE_QUOTES_TERMINATOR}){3}

The | is inside group that is then {3}'d, so it allows either ' or " in groups of three. This is only applies to the sigils. It's correct for normal string and charlist heredocs:

CHAR_LIST_HEREDOC_PROMOTER = {CHAR_LIST_PROMOTER}{3}
CHAR_LIST_HEREDOC_TERMINATOR = {CHAR_LIST_TERMINATOR}{3}

STRING_HEREDOC_PROMOTER = {STRING_PROMOTER}{3}
STRING_HEREDOC_TERMINATOR = {STRING_TERMINATOR}{3}

QUOTE_HEREDOC_PROMOTER = {CHAR_LIST_HEREDOC_PROMOTER} | {STRING_HEREDOC_PROMOTER}
QUOTE_HEREDOC_TERMINATOR = {CHAR_LIST_HEREDOC_TERMINATOR} | {STRING_HEREDOC_TERMINATOR}
