pgsql: doc: Fix example command for ALTER FOREIGN TABLE ... OPTIONS.

doc: Fix example command for ALTER FOREIGN TABLE ... OPTIONS.

In the documentation, previously the example command for
ALTER FOREIGN TABLE ... OPTIONS incorrectly included both
the option name and value with the DROP operation.
The correct syntax for the DROP operation requires only
the name of the option to be specified. This commit fixes
the example by removing the option value from the DROP operation.

Back-patch to all supported versions.
