Upgrade version of nimbus-fml to 93.8.0

[jhugman]

Previous PR #12567 bounced when trying to build Focus on Android on CI only, with not much to go on: Focus live.log; Fenix live.log.

Can build on x86_64 Darwin, but seeing problems on x86_64-unknown-linux-musl.

I'm going to guess this needs investigation around reqwest and TLS in the Application Services repo.

This looks fine to me. My concern was around the TCP experiment with version 93.6.0, but we have that verified, so we can upgrade now.
