Link t the souce code

Hi,

reading this: https://www.postgresql.org/docs/13/install-getsource.html
...
I wonder if the link should not directly point to the relevant release, e.g.:
https://www.postgresql.org/ftp/source/v13.2/

To me that seems to be more convenient than figuring that out on https://www.postgresql.org/download/. The initial page
isabout getting the source code, so links to packages/binaries are not required if someone is looking for the source.  

Thoughts?

Regards,
Daniel
