DOCS: Fix typo in binding-types.md (DOCATT-11249)

[david-beep-one]

Description

Addresses DOCATT-11249, a user-reported documentation feedback ticket.

• The description of the four-way composite binding on the Binding types page repeated a word: "grouped together into into the composite four-way binding." This PR removes the extra "into".

Testing status & QA

Documentation-only change, tested changes locally.

Overall Product Risks

• Complexity: Low – documentation text change only.
• Halo Effect: Low – no code changes; affects only the Binding types manual page.
