Missed typed header value type

Environment

Nodejs v20.15.0

Describe the bug

Since the latest release of unjs/h3 v1.12.0, TypedHeaders 'retry-after' is missing string type:

h3/src/types/_headers.ts

Line 42 in 6765a6e

"retry-after": number;

According to MDN docs, it can take as number (seconds) as well as a date string:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After

Additional context

In Nuxt app, I'm trying to set the response headers by this:

...
setResponseHeader(event, 'Retry-After', (maintenanceDateTo || dateNextDay).toUTCString())

Previously it worked fine since number or string values were valid. Now TS drops an error in a reason described above.

Logs

No response
