Rollup merge of #38163 - durka:patch-33, r=bluss
reference: fix definition of :tt The reference says that $x:tt matches "either side of the `=>` in macro_rules` which is technically true but completely uninformative. This changes that bullet point to what the book says (a single token or sequence of token trees inside brackets).
