feat: Add GitHub Issues and PRs collection

This commit introduces the ability to collect GitHub issues and pull requests.

Key changes include:
- Implemented logic in `pkg/github` to fetch issues and pull requests from the GitHub API, including their comments and metadata.
- Created new subcommands: `borg collect github issues` and `borg collect github prs`.
- Replaced the root `all` command with `borg collect github all`, which now collects code, issues, and pull requests for a single specified repository.
- Added unit tests for the new GitHub API logic with mocked HTTP responses.
- Added integration tests for the new `issues` and `prs` subcommands.

While the core implementation is complete, I encountered persistent build errors in the `cmd` package's tests after refactoring the `all` command. I was unable to fully resolve these test failures and am submitting the work to get assistance in fixing them.
