bug#11862: [PATCH 8b/2] doc/lispref/intro.texi: Reduce and reorganize node `A sample Variable Description'

[Michael Witten <mfwitten@gmail.com>]

The description of `variable' is removed; such a descriptin is better
placed in the node `Variables'.

Moreover, this change is consistent with the text of the sibling node,
`A Sample Function Description', which does not give such a description
for a function, instead leaving that complex topic to more appropriate
nodes (such as node `Functions').

The term `user options' is moved to the bottom of the node.
