Issue checking file

[thomas-lamiaux]

There seem to be an issue with the docker image checking files which may be a bit too old due to web interface as as you can see it bug on a the type scope

   (nat + bool)%type
       : Set
  File "./SearchTutorial.v", line 191, characters 0-19:
  Error: Error: Scope type is not declared.

coq/platform-docs-admins I suggest switching docker to 8.19 as it is the platform version so that it always work with the current version when downloaded, even if the web version bugs at the moment
