fix(docs): correct singular vs. plural mismatch (#1742)

- Changed "Meet Omi, the world’s leading open-source AI wearables that
revolutionize how you capture and manage conversations." to "Meet Omi,
the world’s leading open-source AI wearable that revolutionizes how you
capture and manage conversations."

Reasoning:

- Omi was introduced in the singular ("Meet Omi") but then described as
"wearables" (plural). This caused a mismatch in number agreement.

- If Omi is truly intended to be a single device, this aligns subject
and verb (singular -> “wearable” / “revolutionizes”).

- If Omi is actually meant to be a family of devices, we apologize for
the pull request.
