Support provider: github

Currently, programs need to specify complete URL template.

This is helpful to support all sources. However, most programs come from GitHub releases. Would be nice to have something simplified and auto-detect the common pattern (or lookup from GitHub API), such that the config manifest can look simpler like:

name: myprogram
version: 0.1.0
provider: github
path: myorg/myprogram
overlay:
  Host: https://mygithubenterprise.com  # optional, defaults to "https://github.com"

While the lockfile manifest should remain the same.

(Or at least I don't think there is a need to change it)

Maybe we should do this in baby steps — I think I would be quite happy to have something like this:

name: myprogram
version: 0.1.0
provider: github
path: myorg/myprogram/_/.tar.gz

Which would generate the URL:

https://github.com/myorg/myprogram/releases/download/v0.1.0/myprogram_0.1.0_Linux_arm64.tar.gz

Alternatively, shove them all in overlay section:

name: myprogram
version: 0.1.0
provider: github
path: myorg/myprogram
overlay:
  Host: "github.com"
  Tag: "v{{ .Version }}"
  Separator: "_"
  Ext: ".tar.gz"
  ArchiveNameVersion: "{{ .Version }}"

Relevant-ish: #35

The structure of program configuration was re-done in #54, which now should make it closer to the comment above.
