Subject: fix(tokenizer): don't lowercase temp chars in ScriptDataEndTagName

This bug resulted in e.g. "<script></SCRI" being wrongly tokenized as:

    StartTag(StartTag { name: "script", self_closing: false, attributes: {} })
    Char('<')
    Char('/')
    Char('s')
    Char('c')
    Char('r')
    Char('i')
    EndOfFile

Note that the Char tokens should be uppercase. (This bug could only be
observed when properly doing state switching via tree construction.)
