[release-branch.v0.5] internal/ci: use go1.19.8 for the release of v0.5.0

This intentionally downgrades release-branch.v0.5 to use the go1.19.x
series for releases. The upgrade to go1.20.x was a mistake in
https://cuelang.org/cl/551832.

go1.19.8 (released 2023-04-04) includes security fixes to the go/parser,
html/template, mime/multipart, net/http, and net/textproto packages, as
well as bug fixes to the linker, the runtime, and the time package

Pick up this latest version ahead of our release of v0.5.0.
