Remove git-url-parse dependency

Replace the single usage of git-url-parse (extracting owner/repo from a
git remote URL) with a trivial regex-based implementation in
src/utils/git.ts. Remove both git-url-parse and @types/git-url-parse
from dependencies, and clean up the related dependabot ignore entries.
