Add TimeZone example in doc

[marcflausino]

Hello,

I lost a few hours trying to understand why i got an error like 'No such parameter' while setting 'timezone' with postgresql_set.

Finally i ended up on this post : ansible-collections/community.postgresql#41

I'm sure, many will have the same troubleshoot with that parameter so i guess it would be nice to add an example on the documentation with that TimeZone name, and maybe add an explanation or a warning somehow.

What do you think ?
