[BUG] dda inv install-tools fails with Go 1.24.2

[ravelox]

Following the build instructions for datadog-agent using Go 1.24.2 in README.md, dda inv install-tools generates the following errors:

(.venv) root@vmubuntu:/usr/local/go/src/github.com/DataDog/datadog-agent# dda inv install-tools
go: error loading go.work:
../../go.work:9: unknown godebug "tlskyber"
[1 / 3] Failed running command go install github.com/frapposelli/wwhrd, retrying in 10 seconds
go: error loading go.work:
../../go.work:9: unknown godebug "tlskyber"
[2 / 3] Failed running command go install github.com/frapposelli/wwhrd, retrying in 100 seconds
^X^C
Aborted.

This appears to be related to golang/go#72111

Using Go 1.23.8 works without errors.

Thanks for opening an issue, this is known, as you've seen we're discussing with upstream to get that fixed (golang/go#72111), the best workaround is to export GOTOOLCHAIN=go1.23.8 env variable, it will dynamically downgrade Go to that version when running go commands (and Go 1.23 knows what tlskyber is).
Sorry for the inconvenience...
