Update modules to reduce dependency tree.

[creack]

Run go get -u ./... && go mod tidy

Dep tree generating using modgraphviz / graphviz

go install golang.org/x/exp/cmd/modgraphviz@latest
brew install graphviz
go mod graph | modgraphviz | dot -Tpng -o graph.png

Before:

dot: graph is too large for cairo-renderer bitmaps. Scaling by 0.059917 to fit

After:

This is quite a large leap for a library, is this enforced on us by gRPC? Should we consider moving trail to another module or removing it altogether and vendoring it in teleport?

[creack]

That is enforce by Go. 1.23 will not run the tests for anything lower, complaining about go mod needed tidy and reverting back to 1.22.

[rosstimothy]

I'm exploring removing trail, which pulls in grpc-go in #112. I cannot find any other consumers of the package outside of gravitational.

FYI, I've just landed #113 due to a CVE. It bumps /x/net, Go to 1.20 (required by testify) and a few indirects that also hit on CVEs. It also deletes a lot of lines from go.sum, so I think I've trimmed the dependencies as a side-effect in there.

Closing in favor of #113
