fix: invalid issue template YAML indentation (#9442)

## What changed

Fix the indentation of the final `contact_links` entry in
`.github/ISSUE_TEMPLATE/config.yml`.

## Why

That entry was indented one space too far, which made the issue template
config invalid YAML instead of a valid list item.

## Impact

GitHub can parse the issue template config as intended again.

## Validation

- Parsed `.github/ISSUE_TEMPLATE/config.yml` successfully with Ruby
`YAML.load_file`
