docs: correct default cache path

[razonyang]

May fixes #645, but I'm not sure, since I didn't find any information about this cache path after searching docs, @deining would you mind checking if this PR is OK?

I suspect it makes a difference whether your workflow contains actions/go or not. If actions/go is part of the workflow, the cachedir is /home/runner/.cache/hugo_cache, without actions/go the cachedir is /tmp/hugo_cache_runner.
I created this PR to confirm. @razonyang: Can you please approve this PR and check the results of the workflow run? Thanks!

[razonyang]

@deining You're right, I modified the PR a little more to cover those two use cases.

Hello @razonyang !
We've discussed yesterday on the Hugo's forum about this.
https://discourse.gohugo.io/t/how-to-cache-hugo-modules-in-a-github-action/50334

I'm reaching you because I've also pushed a PR on this repo, trying to fix this with an another approach.

• docs: add env.HUGO_CACHEDIR #650

What are your thoughts?
Warm regards.

@Zer0xxxx GitHub actions can be ran on Windows, there is no /tmp/ on Windows (although other approaches are same), I'd recommend leaving a separate section/paragraph about this approach, rather than deleting previous appraoches, but I'm not maintainer of this repo, you can wait for maintainer to check and reply.

Oh, you're right. I'm dumb, haha!

I don't think this is necessarily a problem, though, since I've specified in the documentation snippets that the action runs on Ubuntu-22.04 (just above the env section).

Documenting absolutely every conceivable use seems to me to be rather complicated, and confusing.

Are there any use cases that I might miss where launching the action in a workflow rather on Windows than on Ubuntu is mandatory?

Are there any use cases that I might miss where launching the action in a workflow on Windows is better than on Ubuntu?

Maybe tests purpose, to make sure the theme works on all supported platforms (Linux, macOS and Windows).

Hmm... Using a matrix, then?
Interesting, I might have a look. I think it is possible to define separate env variables depending on the matrix context.

Should I nail it too? 😉
(Sent you a Discord invite, DM whenever you want a PR from me. I might miss GitHub notifications.)

Lack of time to resolve conflicts, and env approach is not bad, closing this for now.
