[CI] Fix deprecations

Fix multiple deprecations in CI workflows.

### [doctor-rst.yaml](https://github.com/symfony/ux/actions/workflows/doctor-rst.yaml)

```
DOCtor-RST
The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. [...]
```

### [test.yaml](https://github.com/symfony/ux/actions/runs/6209833130/workflow)

Note: ~~the failing php-cs-fixer test is unrelated (cause: new rule in php-cs-fixer)~~
Update: fixed the cs problem, another CI bug appears... not sure if random (does not seem related at all)

```

```
