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

MasaoFujii · MasaoFujii · commit fd3def395081 · 2023-06-08T20:14:10.000+09:00
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.
