[ruff] Fix last_tag/commits_since_last_tag for version command

[ZedThree]

Summary

Since Ruff changed to GitHub releases, tags are no longer annotated and git describe no longer picks them up. Instead, it's necessary to also search lightweight tags.

This changes fixes the version command to give more accurate last_tag/commits_since_last_tag information. This only affects development builds, as this information is not present in releases.

Test Plan

Testing is a little tricky because this information changes on every commit. Running manually on current main and my branch:

main:

# cargo run --bin ruff -- version --output-format=text
ruff 0.9.10+2547 (dd2313ab0 2025-03-12)

# cargo run --bin ruff -- version --output-format=json
{
  "version": "0.9.10",
  "commit_info": {
    "short_commit_hash": "dd2313ab0",
    "commit_hash": "dd2313ab0faea90abf66a75f1b5c388e728d9d0a",
    "commit_date": "2025-03-12",
    "last_tag": "v0.4.10",
    "commits_since_last_tag": 2547
  }
}

This PR:

# cargo run --bin ruff -- version --output-format=text
ruff 0.9.10+46 (11f39f616 2025-03-12)

# cargo run --bin ruff -- version --output-format=json
{
  "version": "0.9.10",
  "commit_info": {
    "short_commit_hash": "11f39f616",
    "commit_hash": "11f39f6166c3d7a521725b938a166659f64abb59",
    "commit_date": "2025-03-12",
    "last_tag": "0.9.10",
    "commits_since_last_tag": 46
  }
}
