Describe the bug

When creating a PR in the browser, gh pr create prints a display URL based on the parsed URL path. For branch names that require URL encoding (for example, quotes), the displayed URL is unescaped and can be invalid.

Affected version

2.85.0

Steps to reproduce the behavior

1. Create and checkout a branch named test-"quoted"-branch-pr.
2. Run gh pr create --web and proceed with the “continue in browser” flow.
3. Observe the displayed URL in the terminal.

Expected vs actual behavior

Expected: the display URL preserves percent-encoding, for example: https://github.com/OWNER/REPO/compare/...test-%22quoted%22-branch-pr

Actual: the display URL is unescaped, for example: https://github.com/OWNER/REPO/compare/...test-"quoted"-branch-pr
