Rollup merge of #123162 - GuillaumeGomez:fix-123158, r=notriddle

Correctly get complete intra-doc link data

Fixes https://github.com/rust-lang/rust/issues/123158.

The problem was that we didn't take into account cases where there would be content other than backticks into the intra doc link definition.
