Update dependencies, rebuild .podspec files (#838)

Motivation:

Our podspec building script relies on Package.resolved, and NIOHTTP2
shipped a podspec fix in 1.12.2; we need pull in that fix to release an
update podspec.

Modifications:

- Update Package.resolved
- Regenerate our .podspec files

Result:

The built podspec is has the right dependencies. Hopefully.
