Doc: improve documentation about where the psqlrc files are.
Remove no-longer-accurate claim that Windows lacks home directories.
Clarify the text by more clearly distinguishing which statements
reflect hard-wired choices versus which ones reflect overridable
defaults. Update the examples of version-specific file names,
and make them track future version changes by using "&majorversion;"
and "&version;". (BTW, in devel and beta releases this method
correctly says that you can use strings like "16devel" and "15beta4"
as minor version identifiers.)
Back-patch to v15, but not further, with the thought that in older
releases the examples with three-part version numbers still had
some historical relevance. v15 will be the first major release after
the last 9.x branch went out of support.
