chore(deps): bump github.com/prometheus/client_golang from 1.21.0 to 1.22.0

[dependabot]

Bumps github.com/prometheus/client_golang from 1.21.0 to 1.22.0.

Release notes

Sourced from github.com/prometheus/client_golang's releases.

v1.22.0 - 2025-04-07

⚠️ This release contains potential breaking change if you use experimental zstd support introduce in #1496 ⚠️

Experimental support for zstd on scrape was added, controlled by the request Accept-Encoding header. It was enabled by default since version 1.20, but now you need to add a blank import to enable it. The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon, golang/go#62513 however, the work took longer than anticipated and it will be postponed to upcoming major Go versions.

e.g.:

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
