Changes

• In lib/docs/scrapers/zig.rb: Updated code attribute of self.links from GitHub to Codeberg, since Zig moved to Codeberg, and used the newly created helper function get_codeberg_tags
• In lib/docs/core/doc.rb: Added the function get_codeberg_tags, similar to the existing function get_github_tags
• In docs/scraper-reference.md: Added documentation for get_codeberg_tags, similar to existing documentation about get_github_tags, with a link to the Codeberg API reference and an example implementation. Additionally, I have noticed that the link for the get_github_tags documentation was outdated, and therefore changed it to the new link
• In test/lib/docs/core/doc_test.rb: Added a new test for get_codeberg_tags, very similar to the existing test for get_github_tags
• In public/icons/docs/zig/SOURCE: Updated the links to the locations on Codeberg

Verification

• bundle exec thor test:all: 0 failures
• curl https://codeberg.org/api/v1/repos/ziglang/zig/tags: returns the
  expected JSON
• New code and icon URLs return HTTP 200
• bundle exec thor updates:check zig: latest version reported as 0.17.1
  from Codeberg:

bundle exec thor updates:check zig

Scope note

self.release is intentionally left at 0.16.0, as CONTRIBUTING mentions that bumping
the version should accompany an actual doc regeneration, which is out of scope
for this migration. bundle exec thor updates:check will now report Zig as outdated.
