RFR: 8358558: (zipfs) Reorder the listing of accessMode property in the ZIP file system's documentation

[Jaikiran Pai]

Can I please get a review of this trivial doc-only change to the `jdk.zipfs`'s documentation? This moves the `accessMode` property listing to the top of the table instead of being at the bottom. With this change, the text about throwing `IllegalArgumentException` when `create=true` and `accessMode=readOnly` has been moved to the `create` property's description.

No functional or specification changes are involved. I verified that the generated documentation looks fine too.
