Update README.md

[toiletsnakes]

the link is broken, 3.3 is the last version of the docs that works.

[Bromeon]

Thank you! Can you use the latest link instead?
https://docs.godotengine.org/en/3.5/getting_started/first_2d_game/index.html

(unfortunately there seems to be no 3.x which automatically points to latest 3.* version)

Also, could you check if there are other occurrences of /stable links across the repo, which need to be updated?
