pg_upgrade doc uses inconsistent versions within the doc.

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/16/pgupgrade.html
Description:

I feel like for readability the pg_upgrade doc should use the same
old_version and new_version examples when showing examples throughout the
doc page.  

as an exmaple I'm looking at :
https://www.postgresql.org/docs/current/pgupgrade.html 

in some places the example commands use v9.6 and v16. (see step 8)

but in other places it mixes versions v9.5 and v9.6 (see step 11 sub step 8)
