fix(session-replay): Fix conversion of frame rate to time interval

[philprime]

When using @_spi(Private) import Sentry it is possible to set a higher frame rate using options.sessionReplay.frameRate = 10.

Due to a UInt / UInt this will result in a time interval since last frame of 0 ms instead of e.g. 100ms.

This PR fixes the division.

No changelog needed because frameRate is internal.

No changelog needed because frameRate is internal.

If I'm not mistaken, this fixes a critical bug. I think this PR is worth a changelog entry.
