composer/composer updated and now conflict with justinrainbow/json-schema and drupal/jsonapi_extras

When attempting to update from 10.5.8 to 10.6.1, after Dec 31, after

https://github.com/composer/composer/commit/fc5a3dd2d79e059b2707f3f2c7a7668fee382345

```
- "justinrainbow/json-schema": "^5.3",
+ "justinrainbow/json-schema": "^6.3.1",
```

... now, a dependency conflict when I try ...

```
$ ddev composer update "drupal/core-*" --with-all-dependencies
Gathering patches from patch file.
> DrupalProject\composer\ScriptHandler::checkComposerVersion
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires drupal/core-dev ^10.5.8 -> satisfiable by drupal/core-dev[10.5.8, ..., 10.6.x-dev].
- composer/composer[2.9.3, ..., 2.9.x-dev] require justinrainbow/json-schema ^6.5.1 -> found justinrainbow/json-schema[6.5.1, ..., 6.6.4] but these were not loaded, likely because it conflicts with another require.
- drupal/core-dev[10.5.8, ..., 10.6.x-dev] require composer/composer ^2.8.1 -> satisfiable by composer/composer[2.9.3, 2.9.x-dev].

Composer [update drupal/core-* --with-all-dependencies] failed, composer command failed: exit status 2. stderr=

```

FYI, more context

```
$ ddev composer why --tree justinrainbow/json-schema

Reproduce the failure with `ddev composer update "drupal/core-*" --with-all-dependencies`, then inspect the dependency tree using `ddev composer why --tree justinrainbow/json-schema`. Compare the requirements from composer/composer, e0ipso/shaper, and drupal/jsonapi_extras; done means the reported dependency conflict is resolved without breaking the update.
