It's nothing to do with version. What you've done is switch from Ubuntu
provided packages to nginx.org provided packages. Ubuntu provides third
party binary modules that are not in the offical repo.
  
The list of offical packges in the repo can be quickly seen by
browsing:
https://nginx.org/packages/mainline/ubuntu/pool/nginx/n/

For Lua (and Luajit) you can build from source using make files from
the nginx offical packaging mercurial repo:

https://hg.nginx.org/pkg-oss/file/1c4041361462/contrib/src
https://hg.nginx.org/pkg-oss/file/1c4041361462/build_module.sh 
(1.25.3 commit)

There are many other useful modules there too that are not shipped as
binaries.  

However, I don't believe lua-sql-mysql is included there, so you will
still need to build that from sources on github:
