Otl go 1.20

Go 1.20 is released!

[jeffreyc-splunk]

Need to also update the versions for CI. See #2493.

@rmfitzpatrick,
It seems go 1.20 has major memory leak issues with running with the go 1.19 golangci-lint module.
golangci/golangci-lint#3535

Trying to run make commands that execute “go mod tidy -compat=1.19” and golangci-lint causes memory usage to go up +50gb on my local machine and CI/CD steps to fail.

This seems like a blocker for upgrading at the moment. Will likely close this pull request later unless advised otherwise.

Do you see this happen on CI too? I see some development around this issue here: golangci/golangci-lint#3414

Specifically this comment:

I guess you are installing golangci-lint with brew, brew uses go1.19 instead of go1.20.
golangci/golangci-lint#3565 (comment)

So you have to use either our binaries or our Docker image or build/install golangci-lint with go1.20.

golangci-lint requires to be built with go1.20, without that golangci-lint cannot work with go1.20.

Note the latest version of golangci-lint is v1.51.1.

Yeah it breaks CI/CD by causing the pipeline to timeout or get killed.

Closing this PR for now. Will add Go 1.20 support in the future.
