[BUG] Incorrect link in "Build a Crossword Game" tutorial

[LStan]

Describe the bug 🐞
There is a wrong link to https://github.com/near-examples/rust-template/blob/3f3a8cfa19eb4bd15ae1c410fed136c6c7ac97a0/src/lib.rs#L1-L38 on the bottom of the page https://docs.near.org/tutorials/crosswords/basics/set-up-skeleton

Expected behavior
The link above was changed to another repo a few months ago (9faa8cf)
Probably the wrong link should be changed to a file in that repo.
