feat(ios): add minutes text style to Timer

[Titozzz]

What is this?

Timer gets a new textStyle: 'minutes' option. It shows a live countdown or count-up without seconds, for example "19 minutes" instead of 19:42. Seconds are often noise in Live Activities that track something on the scale of minutes or hours, such as a shift or an appointment starting soon. Until now, the only live-updating styles ('timer' and 'relative') both showed seconds.

How does it work?

On iOS 18 and later, the timer renders Text(.currentDate, format: .offset(to:allowedFields:sign:)). This is SwiftUI's SystemFormatStyle.DateOffset, which the system keeps up to date on its own, just like Text(timerInterval:), with no push or app update needed. The allowed fields are minutes only, or hours and minutes when showHours is set. The sign is hidden, so countdowns and count-ups read the same way. The target date follows the same rules as the 'relative' style: the end of the interval when counting down, the start when counting up. The output is localized by the system.

On earlier iOS versions, 'minutes' falls back to the existing 'timer' style. The schema, the generated TypeScript and Swift parameter docs, and the website's Timer documentation are updated to match.

Why is this useful?

Apps can show a calm, readable "Starts in 19 minutes" or "Started 12 minutes ago" in Live Activities and widgets that still updates on its own. That matches how people think about longer intervals. Before this, apps had to choose between a ticking mm:ss clock and static text that goes stale.
