Thanks for the PR. Please change your description to match the pull request template we have: https://github.com/home-assistant/core/blob/dev/.github/PULL_REQUEST_TEMPLATE.md
You can copy out the "raw" text, paste it in your description, and update it accordingly.

For dependency bumps, you'll see what you need to do in the template itself, like:

• For the updated dependencies - a link to the changelog, or at minimum a diff between library versions is added to the PR description.

  Updated by running python3 -m script.gen_requirements_all.

You still need to do both of this.
