feat: Added two github helper for retrieving specific release instead of latest release.

[pix]

I've added a new feature that lets users download specific versions of GitHub releases, eg:

.local/bin/delta:
  type: archive-file
  url: {{ gitHubReleaseAssetURL "dandavison/delta" "0.16.5" "delta-*-x86_64-unknown-linux-musl.tar.gz" | quote }}
  executable: true
  stripComponents: 1
  path: delta

I included a quick test and doc.

Feel free to tell me if anything else needs adjustments.

Thanks for this. Please add a new bucket for the new state, rather than mixing everything in a single bucket.

Thank you, this looks excellent. I want to do a final review tomorrow, but it all looks good. If you want to run the full set of checks locally (e.g. to fix the whitespace errors) you can run make smoketest.

What do you think about allowing some "magic" value for downloading the latest release ?

Use case:

some-external:
  url: {{ gitHubReleaseAssetURL "user/repo" .data.versions.repo (printf "repo-*-%s-unknown-linux-musl.tar.gz" $arch) | quote }}
----
data.yaml:

data:
  versions:
      repo: latest # Fetch the lastest release (masks any "latest" tag existing on the releases)
      chezmoi: v2.51.0

Maybe just something like:

func (c *Config) gitHubReleaseAssetURLTemplateFunc(ownerRepo, version, pattern string) string {
	if version == "latest" {
		return c.gitHubLatestReleaseAssetURLTemplateFunc(ownerRepo, pattern)
	}

I fixed the whitespace issues (and reworded a bit)

There's gitHubLatestRelease for this, or am I missing something?

The function name in the new tests is incorrect.

The function name in the new tests is incorrect.

Thanks, I'm fixing this. The tests weren't running because they only run when the CHEZMOI_GITHUB_TOKEN environment variable is set, as they make requests to the GitHub API which has very low rate limits if you don't authenticate.
