Add optdepends for modules

Description:

Hugo can use optional modules which it will install automatically when called. However it requires other software to do so, e.g. go to install go modules.

Additional info:

• package version(s): 0.145.0-1
• config and/or log files: https://github.com/matrix-org/matrix-spec/blob/main/config/_default/hugo.toml
• link to upstream bug report, if any: n/a

Steps to reproduce:

1. Uninstall go, install hugo (this package)
2. Run hugo serve on a project using modules, e.g. https://github.com/matrix-org/matrix-spec uses github.com/matrix-org/docsy
3. Error: command error: failed to load modules: failed to download modules: binary with name "go" not found in PATH

Hi ,

Thanks for the report!

However it requires other software to do so, e.g. go to install go modules.

It is unclear to me if adding "go" as an optional dependency is enough to cover your point. The above sentence seems to imply there might be other packages that could be required for other optional module types. If so, do we have a list somewhere? Otherwise I don't think we can reasonably predict whatever dependency every optional modules may require inside an exhaustive list of optional dependencies.
