Looks good to me.
FYI: the default PHP version in the docs is still 8.1:

ddev/docs/content/users/configuration/config.md

Line 414 in df3bfed

| :octicons-file-directory-16: project | `8.1` | Can be `5.6`, `7.0`, `7.1`, `7.2`, `7.3`, `7.4`, `8.0`, `8.1`, `8.2`, or `8.3`.

ddev/docs/content/users/extend/customization-extendibility.md

Line 12 in df3bfed

The project's `.ddev/config.yaml` file defines the PHP version to use. The [`php_version`](../configuration/config.md#php_version) can be changed to `5.6`, `7.0`, `7.1`, `7.2`, `7.3`, `7.4`, `8.0`, `8.1`, `8.2`, or `8.3`. The current default is `8.1`.
