[NET-4968] Upgrade Go to 1.21 (#20062)
* Upgrade Go to 1.21

* ci: detect Go backwards compatibility test version automatically

For our submodules and other places we choose to test against previous
Go versions, detect this version automatically from the current one
rather than hard-coding it.

# We use .go-version as our source of truth for current Go
# version, because "goenv" can react to it automatically.
#
# In the future, we can transition from .go-version and goenv to
# Go 1.21 `toolchain` directives by updating this workflow rather
# than individually setting `go-version-file` in each `setup-go`
# job (as of 2024-01-03, `setup-go` does not support `toolchain`).
#
# When changing the method of Go version detection, also update
# GOLANG_VERSION detection in the root Makefile; this is used for
# setting the Dockerfile Go version.
