Extend hermit info to display all version information

[alecthomas]

It currently only displays either the current version, or the version that would be installed.

I was thinking of creating an issue about having the installed version shown for hermit list and hermit status as well, but I'll ask here first: what do you think, @alecthomas?

I've installed most packages using <package name>@latest and when doing either of the aforementioned commands I have no insight into what is the version that is actually installed without doing hermit info and looking at the "Source" row. I'd be more than happy to take this on myself, but would want to clarify the expected output in all cases.

Maybe for hermit info it could be, for example:

 Channel: latest
 Description: Terraform is an open-source infrastructure as code software tool...
 Homepage: 
-State: installed
+State: installed: 1.3.6
 Source: https://releases.hashicorp.com/terraform/1.3.6/terraform_1.3.6_linux_amd64.zip
 Root: /home/usrme/.cache/hermit/pkg/terraform@latest
 Binaries: terraform

For hermit list it could be:

-terraform (@latest)
+terraform (@latest: 1.3.6)
   Terraform is an open-source infrastructure as code software tool...

For hermit status it could be:

 Packages:
-  terraform@latest
+  terraform@latest:1.3.6

[usrme]

Mentioning you again, @alecthomas, in the hopes of finding out what you think about the above. I'm still very much interested in tackling this.

When I do hermit info I get this:

🐚 ~/dev/ftl $ hermit info go
Name: go
Version: 1.21.0
...

Is that not what you want?

[alecthomas]

Oh you're talking specifically about channels!?

Yeah that would be useful info agreed.

[usrme]

Maybe you could talk a bit more in-depth about what you meant in the original issue, we clearly deviated in our understanding of things and can maybe converge 😄

[alecthomas]

I think the original intent was that hermit info should show all available versions, in addition to just the current or latest. But showing the underlying version of a channel would be useful too.

[usrme]

By all available versions you mean the versions that could be installed, i.e. the same set of versions as discovered by hermit search? 🤔 I think this would mean that hermit info would take more time to execute to grab the same information as hermit search.

Or is there a way to query locally installed versions and list those, i.e. those which could be installed directly from cache?
